Hi L~R. Im just curious about one part of your solution: 

    for ( sort { $data[$a]->[2] <=> $data[$b]->[2] } 0 .. $#data ) {
        print join "\t" , @{ $data[$_] };
        print "\n";
    }

Why did you code it this way I wonder? It seems odd that you are actually sorting a list of indexes and not the elements themselves. Theres no speed gain, in fact theres a loss in that each element requires two levels of dereferencing, and you have the added memory hit of constructing a list of indexes. Im really curious if there was any reason why you didnt just say 

print join("\t",@$_),"\n" for sort { $a->[2] <=> $b->[2] } @data;

or possibly: 

print join "\n",map { join "\t",@$_ } sort { $a->[2] <=>$b->[2] } @dat
+a;
