Thanks to Brian and Jacque, who supplied the key piece of information
that the docs don't make clear. The Rev dictionary vaguely says "To
create a custom sort order, use the each keyword to pass each line or
item to a custom function. The value returned by the function is used
as the sort key for that line or item." Brian and Jacque put it much
more clearly:

See if this helps - the idea is you need your function to return
the position you want that item in.

The way it is now, termOrderSort is returning a number from the
item list (such as 259), and the lines will sort numerically using
those numbers. What you want is for "259" to be returned as "1" and
"26" to be returned as "2", etc. Then the sort works.

Using "word 1 of each" sends the actual number in your raw data to
the sort function. The sort function gets the item offset of that
number from the sort order list. It returns that offset as an
integer that will force the data to sort in the proper order; that
is, "259" becomes "1", etc.
I only had to make a minor change for it to work properly after their
suggestions:
local lSortOrder -- this is the only local you need
on updateList
put the rawLessonData of fld "vocablist" into tRawData
put "259,26,110,111,272,314,149,250,54" into lSortOrder
sort lines of tRawData by termOrderSort(word 1 of each)
-- do stuff with the sorted list
end updateList
function termOrderSort tNum
set the wholeMatches to true ## otherwise '7' matches, '267', etc.
return itemoffset(tNum, lSortOrder) -- this returns "1,2,3,4,5,etc"
end termOrderSort
Thanks for the help!
