I think that you are thinking of the Guttman-Rosler Transform?

Agreed. BTW I believe the GRT is generally faster than the Schwartzian Transform (this node has more detail on sorting history in Perl).

Though fond of the GRT, I couldn't make it work for this problem because of the unusual requirement to sort descending by count yet ascending by name (it would work nicely to sort both fields ascending via the classic pack "NA*" trick). If anyone can see a way to make GRT work for this problem, please let us know.
