I'm confused, IMHO "Schwartzian Transform" and "Decorate-Sort-Undecorate" are two names of the same thing ... right ???

EDIT: see also Decorate-Sort-Undecorate in WP.

UPDATE: OK I got it. You were referring to GRT beeing faster. =)

(Advanced Sorting - GRT - Guttman Rosler Transform)

Well in this case creating a float separating the two numeric values by a point should be fast enough.
