I suppose that if I sorted before calling language_strings, I would get "Spanish, Latin" because of "esp, lat", which wouldn't match the alphabetically sorted "Latin, Spanish".

You are correct. The code I supplied would not work for that reason.

Why do you start with "{#original:"? That field is never used in the functions (the token $ does not appear). You could use "{:" and make it clear that there is no field being passed into the functions.

I am considering adding a "list_equal" function, where two lists are considered equal if they contain the same items in any order (case insensitive compares). That would get rid of the list_sorts, which are superfluous in this case. One question: I would assume that both lists have the same separator, making the call something like

list_equal(list1, list2, ',', yes_value, no_value).

What do you think?
