Picking out the sort from the tangle of unformatted code I see: 

 my @temp = reverse sort { $a->[0] cmp $a->[0]} @results;

If you compare $a->[0] against $a->[0], it will always be equal, so sort will do nothing. Is that the problem you are experiencing?

Try replacing one of the $a with $b and see what difference it makes.
