This is fine as far as it goes, though in my specific use case it has to
be a bit more complicated, since I need to both preserve the initial
list and do case insensitive sorting.  This added complication is what
prompted my post, since if it were possible to apply text-changing
functions to widgetized buffers, I would only need to set sort-fold-case
and call sort-lines.  But since this apparently is not possible, I have
indeed resorted to the pre-sorting, despite its additional slight
overhead.
