Providing the following just because I'm slow and it might help someone else as well. I had to reformat your code in order to "see" it ;) and added some comments just because.

my @s = map  { $_->[1] }               # get back the original value (
+$_ from the third step in the map)
        sort { $a->[0] <=> $b->[0] }   # sort on $1 from below
        map  {
               $c += 1;                # count the regexs
               /(\d+)/;                # put the digits from $_ into $
+1
               [ $1, $_ ]              # store $1, and $_ for later re
+trival
             } @l;

I liked the benchmarking code too, very nice setup. ;)
