You probably want to do 
$referrers[$cnt] = [ $element, $name, $count ];
$cnt++;

instead. Actually, scratch that, you want push @referrers, [ $element, $name, $count ];

Avoid index variables in Perl whenever possible (which is very nearly always due to push, pop, shift, unshift, splice and foreach) - they are a source of "one off" mistakes. Plus, the array operators are more efficient.

Anyway, using anonymous arrays, sorting becomes trivial: my @sorted_referrers = sort { $a->[2] cmp $b->[2] } @referrers; For the record, here's a simple version that will do this using your code and split: my @sorted_referrers = sort { (split("|", $a))[2] cmp (split("|",$b))[2] } @referrers; The following is a much more efficient way to do it: 
my @sorted_referrers =
    map { $_->[1] }
    sort { $a->[0] cmp $b->[0] },
    map { [ (split("|"))[2], $_ ] } @referrers;

But honestly, it is nonsense to jump through all these hoops to work with stringified data when you have it available in native form to begin with.

Makeshifts last the longest.
