Please see Re: Change elements order in an array. This node has been merged with it, and this one will be reaped.

Per part of my post in Re: Change elements order in an array, you're wanting to modify the inner arrays. This will work. Just put your original data back in. It iterates over @AoA, and for each array reference within it, slices it to the specified order, then pushes those results within a new array reference onto the @new_aoa structure.

my @new_order = (0, 1, 2, 3, 5, 4);

my @AoA = (
  [
      qw(1 2 3 4 5 6),
  ],
  [
      qw(a b c d e f),
  ],
);

my @new_aoa;

for (@AoA){
    push @new_aoa, [@$_[@new_order]];
}

print Dumper \@new_aoa;
