Is there a function that sorts a list into a user-defined order?

Context: I have a text column that may return results in a list-string like "foo, bar, foo, foo, foobar."

Using Action Chains, I'd like to:
a) Sort the entries in a user-defined order (e.g. "foobar, bar, foo, foo, foo)
b) Select the first item of this sorted list

And then replace the string with that.

(Additional context: When FanFicFare downloads an anthology of multiple fics, it concenates all the ratings into an unsorted string like "General Audiences, Mature Audiences, Explicit, Teen and Up Audiences, Not Rated." In order, I want to pick the first of Explicit > Mature > Teen > General > Not Rated.)

edit: can I check just one column with a first_non_empty?
