Thanks for the response.
In my current case, fld 2 has short, one-word 'tags', so
get fld listToSort
repeat with x = 1 to the number of lines in it
   put line x of fld 2 & " " before line x of it
end repeat
sort it descending by word 1 of each
repeat for each line LNN in it
   put word 2 to -1 of LNN & CR after finalOrder
end repeat
delete last char of finalOrder
put it into fld listToSort
Which is fast enough for my very small data blocks.
My next task this evening is waaay more data to sort.
