sorting by hash value

hi

is it possible to sort by the values in a hash if those values might
be identical ?
please try example below whcih will indeed sort the way i want, but
will (obviously) discard duplicate keys in my reverse hash;

anyone have a good idea for this ?

%test = (
    abc => 1230,
    def => 456,
    cbs => 456,
    agr => 111,
);

my %reverse_test = reverse %test;
my @sorted_keys = sort { $a <=> $b } keys %reverse_test;

foreach my $key (@sorted_keys) {
    print "$key => $reverse_test{$key}\n" 
}
