This is the best I could come up with. This assumes you've already sorted the cards.

#!/usr/bin/perl -w

use strict;

my $hand = "33447";

# Check the hand for each card
foreach my $card (2..10, "J", "Q", "K", "A")
{
    # Count the number of cards in hand, by substituting each with its
+elf
    # and getting the number of substitutions
    my $numCards = $hand =~ s/$card/$card/g;
    
    # Substitute the groups of similar cards with their quantity
    $hand =~ s/$card+/$numCards/g;
}

print $hand;

There is probably a more compact solution out there. :)
