Does this work for you?

use strict;
use Data::Dumper;

my @data;

while (<DATA>) {
    chomp;
    push @data, [ split '\s', $_ ];
}
@data =  sort { $a->[1] <=> $b->[1] or
                $a->[2] <=> $b->[2] } @data;
print Dumper \@data;
__DATA__

I'm not sure what you meant by having 'A' in the third column disregarded. If you meant you didn't want it in the data, change the while loop to the following:

while (<DATA>) {
    chomp;
    push @data, [ split '\s', $_ ];
    $data[ -1 ][ 2 ] = substr( $data[ -1 ][ 2 ], 1 );
}

If you want it included but disregarded in the sort, change the sort to the following:

@data =  sort {         $a->[1]     <=>         $b->[1] or
                substr( $a->[2], 1) <=> substr( $b->[2], 1) } @data;
