Here is are two versions of updated scripts.

Note that in both versions, the command to initiate a nudge has been changed to:

/nudge <target>

The -1 was unnecessary, so I removed it.

Code:
on *:TEXT:$($me):*:nudge $target

;/nudge 'shakes' the target window when target is minimized, maximized or normal
alias nudge {
  var %nsound = sounds/nudge.wav
  ;-----------------------------------------------------
  ;1=target, 2=count, 3=x, 4=y, 5=ticks, 6=msec, 7=state, 8=astate, 9-=active
  if ($2 == $null) {
    var %x = $iif($window($1).x < 0,0,$v1)
    var %y = $iif($window($1).y < 0,0,$v1)
    var %s = $window($1).state
    if (max isin %s) %s = -x
    elseif (nor isin %s) %s = -r
    else %s = -
    var %a = $window($active).state
    if (max isin %a) %a = -ax
    elseif (min isin %a) %a = -an
    elseif (nor isin %a) %a = -ar
    else %a = -
    .timer -m 1 1 nudge $1 0 %x %y $ticks 750 %s %a $active
    if ($exists(%nsound)) splay $qt(%nsound)
    return 
  }
  if ((!$window($1)) || ($7 == $null)) return
  var %x = $3, %y = $4, %o = 4
  if ($calc($ticks - $5) > $6) { 
    window $1 %x %y 
    if (($9- != $1) && ($9- != $null)) window $8 $qt($9-)
    if ($7) window $7 $1
    return
  }
  elseif ($2 == 0) { inc %x %o | inc %y %o }
  elseif ($2 == 1) { dec %x %o | inc %y %o }
  elseif ($2 == 2) { inc %x %o | dec %y %o }
  elseif ($2 == 3) { dec %x %o | dec %y %o }
  elseif ($2 == 4) { dec %x %o | inc %y %o }
  elseif ($2 == 5) { inc %x %o | dec %y %o }
  $+(.timer.nudge.,$1) -m 1 30 nudge $1 $calc(($2 + 1) % 6) $3-
  window -ar $1
  window $1 %x %y
}

This version will shake the target window regardless of the target or active windows' states. The active window is restored to its previous state after shaking is complete.

Code:
on *:TEXT:$($me):*:nudge $target

;/nudge 'shakes' the target window when target is minimized or normal only
alias nudge {
  var %nsound = sounds/nudge.wav
  ;-----------------------------------------------------
  ;1=target, 2=count, 3=x, 4=y, 5=ticks, 6=msec, 7=state, 8=astate, 9-=active
  if ($2 == $null) {
    var %x = $iif($window($1).x < 0,0,$v1)
    var %y = $iif($window($1).y < 0,0,$v1)
    var %a = $window($active).state
    if (max isin %a) return
    elseif (min isin %a) %a = -an
    elseif (nor isin %a) %a = -ar
    else %a = -
    var %s = $window($1).state
    if (max isin %s) return
    if (nor isin %s) %s = -r
    else %s = -
    .timer -m 1 1 nudge $1 0 %x %y $ticks 750 %s %a $active
    if ($exists(%nsound)) splay $qt(%nsound)
    return 
  }
  if ((!$window($1)) || ($7 == $null)) return
  var %x = $3, %y = $4, %o = 4
  if ($calc($ticks - $5) > $6) { 
    window $1 %x %y 
    if (($9- != $1) && ($9- != $null)) window $8 $qt($9-)
    if ($7) window $7 $1
    return
  }
  elseif ($2 == 0) { inc %x %o | inc %y %o }
  elseif ($2 == 1) { dec %x %o | inc %y %o }
  elseif ($2 == 2) { inc %x %o | dec %y %o }
  elseif ($2 == 3) { dec %x %o | dec %y %o }
  elseif ($2 == 4) { dec %x %o | inc %y %o }
  elseif ($2 == 5) { inc %x %o | dec %y %o }
  $+(.timer.nudge.,$1) -m 1 30 nudge $1 $calc(($2 + 1) % 6) $3-
  window -ar $1
  window $1 %x %y
}

This version shakes the target window only when neither the target nor active windows are maximized. This version is meant to shake when the user has their windows tiled/cascaded/unmaximized. If the active or target window (all windows) are maximized, the /nudge alias exits without shaking. Personally, this is the version I would use if I were to use this script myself.
