Bielie, I don't know where you get the idea for the quit event with a # prefix to it. There's no $chan in the quit event. You either need to put the #chan by itself or loop through the $comchan:

on !*:part:#:{
  inc $+(%,p,#,$nick)
  inc $+(%,p,$nick)
  msg # $($+(%,p,$nick),2) has parted # $+ .  $&
    $nick has parted $iif($($+(%,p,#,$nick),2) = 1,$v1 time.,$v1 times.)
}
on !*:quit:{
  var %q $comchan($nick,0)
  while (%q) {
    if $me ison $comchan($nick,%q) {
      inc $+(%,q,$v2,$nick)
      inc $+(%,q,$nick)
      msg $v2 $($+(%,q,$v2,$nick),2) has parted $v2 $+ .  $&
        $nick has quit $iif($($+(%,q,$v2,$nick),2) = 1,$v1 time.,$v1 times.)
    }
    dec %q
  } 
}
