I have a question for the Wise Perl Monks, thanks in advance. I am using map and sort to sort by 2 columns. The trouble I am having is, it does sort the first column but it will not sort by any other column when I change the number. The list has numbers to sort. This is delimited by tab. What am I doing wrong?

my @sorted = map {$_->[0]}
             sort { $a->[0] <=> $b->[0] ||
             sort { $a->[1] <=> $b->[1] }
             map {chomp;[$_,split(/\t/)]} <FILE>;
print OUT "$_\n" for @sorted;
