On me it's working perfect, try use this code, i am sure that you have a duplicate of an alias.

Code:
alias -l addPoints {
  if ($1 !isnum) { echo 2 -st $1 is not a number. It needs to be a number. | halt }
  var %topic $+($chan,.,$nick)
  var %points $calc($readini(Points.ini,%topic,Points) + $1)
  writeini -n Points.ini %topic Points %points
  return %points
}
alias -l lookUpPoints {
  var %topic $+($chan,.,$nick)
  var %points $readini(Points.ini,%topic,Points)
  return %points
}
alias doaddpoints {
  if ($3 !isnum) { echo 2 -st $3 is not a number. It needs to be a number. | halt }
  var %topic $+($1,.,$2)
  var %points $calc($readini(Points.ini,%topic,Points) + $3)
  writeini -n Points.ini %topic Points %points
  echo -a Added points for %topic
}
alias dorempoints {
  var %topic $+($1,.,$2)
  remini -n Points.ini %topic Points
  echo -a Removed points for %topic
}
on *:text:!points:#:{
  if ((%floodpoints) || ($($+(%,floodpoints.,$nick),2))) { return }
  set -u10 %floodpoints On
  set -u30 %floodpoints. $+ $nick On
  msg # $nick has $iif($readini(Points.ini,$+(#,.,$nick),Points),$v1,0) total points.
}
on $*:text:/!points (add|remove|del)/Si:#:{
  if ($nick isop #) {
    if ($0 < 3) { msg # Insufficient parameters: Use !points <add|remove|del> <user> [number] | return }
    writeini -n Points.ini $+(#,.,$3) Points $calc($readini(Points.ini,$+(#,.,$3),Points) $iif($2 == add,+,-) $iif($4 isnum,$4,1))
    msg $chan $3 now has $readini(Points.ini,$+(#,.,$3),Points) total points. 
  }
  else { msg $chan This command is only available to moderators. }
}
