To add to my previous in this thread :

In that case, it should be faster if you compute for each sortable datum
of a column a sort key, attached to the datum, of such a nature that the
many comparisons used in sorting reduce to a simple comparison of
values, as a result of which the datum-key pair may be swapped as a
unit.

For example, if sorting European date strings such as 24/7/2012,
rearrange into an ISO-8601 form, 20120724 for the key.

If Elegie has a little time to spare, an E-mail to me could cure that.
