I like sorting an array of indices for stuff like that: 

    my @data= ([...],[...],...);
    my $idx= 3;
    my @idx= sort {
        $data[$a][$idx] <=> $data[$b][$idx]
    }, 0..$#data;
    for my $row (  @data[@idx]  ) {
        for my $value (  @{$_}  ) {
            ...
        }
    }
# or
    print $q->table(
      map {
        $q->Tr(
          map {
            $q->td($_)
          } @{$_}
        )
      } @data[@idx]
    );

That way you can use an array slice to get each column in the "sorted" order. Though, with each record held in single anonymous array, it has little advantage (unless you wish to keep track of the "original" order for some reason).

As for figuring out complex data structure dereferencing syntax, I found that References Quick Reference made it so I never had any problems with that again.
