Rather then trying to do it that way, consider this.

Set a variable such as %paused when using the /splay pause command. Then just have your alias just return $true if the variable exists.

Example:
Code:
alias pause.mp3 {
  if ($paused == $false) { set %pause 1 | splay pause }
  else { unset %pause | splay resume }
}
alias paused {
  return $iif(%pause == 1,$true,$false)
}


It's what I've been using for years and has never failed.
