I would put some print statements in there to verify that the variables
contain what u think they contain. Also Data::Dump::pp is ur friend.
e.g. print "\$top: $top\n";
Another thing I noticed. Normally u want "opendir DIR, $top", not $DIR. If
$DIR is undef, that code will fail. A best practice is to always have an
else{} block after any if{} blocks to catch and debug errors. The same goes
for unless{} blocks. Use if(not..){} so u can use the else{} to catch errors.
