I have a hash of arrays of the following structure... 
%HoA = (
    part1     => [
        'Sc',
        'John',
        'Jacob',
        'Jingle'
    ],    
   part2      => [
       'Sc',
       'Diffie',
       'Whitman'
   ]
   jpart3     => [
       'Mo',
       'Diffie',
       'Duffy'
   ]
);

I am able to sort by keys using... 
sub sort_keys_ascending{
  sort keys %HoA
}

and I am able to sort by value using... 
my $href = \%HoA;
sub sort_typeparm_ascending{
  sort{
        $href->{$a}[$col_id]
          cmp
        $href->{$b}[$col_id]
      }
      keys %data
}

The problem arises when I want to sort by value, then by the key itself... 
sub sort_typeparm_descending{
  sort{

        $href->{$b}[ 0 ]
          cmp
        $href->{$a}[ 0 ]
           ||
        ????? KEY{$b} ?????
          cmp
        ????? KEY{$a} ?????


      }
      keys %data;
}

Do you fellas know if it's possible to do it in this format or am I completely on the wrong path? I can't find any info on how to do this. Thanks in advance, Deke
