How about this? 
use strict;
use warnings;
use Data::Dumper;;

my %hash = (
    A => [1,2],
    B => [4,6],
);

# just to see what we have
print Dumper \%hash;

# and this prints what you want (i think)
print "$_ => @{ $hash{$_} }\n" for sort keys %hash;

I always bring Data::Dumper along for the ride when i deal with complex data structures such as this.

B--B--B--B--B--B--B--B--
