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.
