What I do is have a field in the data that the user never sees, numbering
the records in their "natural" order. When the user asks to see the records
in "natural" order, I simply sort on that field.

That is a completely different issue (an interface issue); I have no answer
to that. I don't know how you would make clicking on a column header turn
off sorting in that column. m.
