Um, that tag is the "name", and if you change that, the name in CREATE
FUNCTION also changes. I was initially thinking in that direction, but
it seems it won't be feasible without significant refactoring.
In the mean time, hacking it into the sort function itself as a special
case works out fine, per attached patch. One might frown upon such an
exception, but then again, function overloading is an exception to the
one-name-per-object rule all over the place anyway. ;-)
