That's far too complicated a solution for me to leave standing after a code review if I was doing this formally.

If you merely want to avoid processing items based on their value, use a next in a foreach: 

for $item (@list) {
  next if $item == 2 or $item == 4;
  ... rest of processing ..
}

If you want a list that contains all but those items, then use a grep, as you said: 
my @newlist = grep { $_ != 2 and $_ != 4 } @list;

But your for-loop monstrosity is ripe for off-by-one errors, and even if you got everything just right, your maintenance programmer would almost certainly break it.

Extra special hint: walking a list with for-style loops is almost always WRONG. Yes, there are counterexamples, but start with that.
