That's missing the final newline (a common mistake). Perhaps you wanted: 
open RESULTS, ">$results_file" or die;
print RESULTS "$_\n" for @results;
close RESULTS;

And as for: 
  $access{$_}{old} ||= 0;               # defaults to avoid warnings
  $access{$_}{new} ||= 0;
  if ($access{$_}{old} > $access{$_}{new}) {
        push @results, "$_";            # keep results rather than pri
+nting
  }

I'd recast that as: 
  if (($access{$_}{old} || 0) > ($access{$_}{new} || 0)) {
        push @results, "$_";            # keep results rather than pri
+nting
  }

mostly because I hate changing values when all I'm really trying to do is test them. One of the many reasons why I'm not religious about enabling -w.
