I agree that tie is inefficient. But it is a constant factor overhead - your code is slower but still scales reasonably. I draw a big distinction between that and algorithmic inefficiency which can cause code to fall over surprisingly fast.

As for the API, pass me the information any way you want. All of the options that you mention are supported if I get the following information: 

my $cmp = sub {
  my ($key_a, $value_a, $key_b, $value_b) = @_;
  # do some comparison
};
