Well, assuming you have a use strict; that you did not include in the code sample then %count is not being explicitly defined. You are declaring $count, but you are using it as a hash, $count{$word}. Change $count to %count and it should be okay.

my(@words, %count, $word);

Update: added explicit example of where to make the change.

On time, cheap, compliant with final specs. Pick two.
