Please see How do I change/delete my post? and use <code> tags to format code, sample input, and expected output. Fixed by GrandFather.

Anyway, here's a pure-Perl solution. It doesn't actually sort the matrix, it just gives you the sorted indicies of the rows, but that's enough to get your expected output, and hopefully you can see how to use the output to reorder the matrix if you like*.

#!/usr/bin/env perl
use warnings;
use strict;
use Data::Dump;

my @matrix = (
    [qw/ t1 t1 t2 t2 t1 t2 /],
    [qw/ a1 a2 a1 a2 a3 a3 /],
    [qw/ mis mis mis mis del del /],
);

my @idx = sort { $matrix[0][$a] cmp $matrix[0][$b]
    or $matrix[1][$a] cmp $matrix[1][$b] } 0..$#{$matrix[0]};
dd @idx;  # (0, 1, 4, 2, 3, 5)
my @out = map { $matrix[2][$_] } @idx;
dd @out;  # ("mis", "mis", "del", "mis", "mis", "del")
