You made no mention of the data structure representing each hand (nor does
it sound like the code representing them counts in the printing).

Here's my code for the hands:

  @H = (
    [qw( AQJ83 KJ6   5     AQJ5 )],
    [qw( T6542 AT    QT762 4    )],
    [qw( K9732 9     974   A983 )],
    [qw( K7    Q8532 KJ4   T86  )],
  );

Yes, they're already sorted, and they're kept as strings.  If you want an
implementation using a hash of array refs, blah.

And here's the printer:

$A=(' 'x13).'@: @<<<<<<<<<<<<'."\n";$B='@: @<<<<<<<<<<<<       @: @<<<<<<<'.    
'<<<<<'."\n";for(@C=(S,H,D,C)){formline($A,$_,$H[0][$i++])}$^A.="\n";for(@C)
{formline($B,$_,$H[1][$j++],$_,$H[2][$j-1])}$^A.="\n";for(@C){formline($A,$_
,$H[3][$k++])}print$^A;

It's not beautiful, but it does the job.
