It could be that if the program is storing the value of: 
my $comments = $q->escapeHTML( $q->param('comments') ) || '';

[download]
into a DB and if the user is writing something like in this string: "That's my option and <script>TEST</script>". The value will be stored in a save format like:
"That's my option and <script>TEST</script>".
Tha's why I think is the reason, and why not?
