I got that mixed up indeed, apologies! The manual does mention it, but perhaps not in the easiest searchable way:

3.347. sort_aux

(...)
You can also specify the “last-” prefix in addition to the “reverse-” prefix, but “last-” must come after “reverse-”. The “last-” prefix causes messages to be sorted against its siblings by which has the last descendant, using the rest of $sort_aux as an ordering.

Glad to hear this works for you!
