Alphabetize Rollup Result

I am doing a rollup on a field that has text (2-letter US State):
ARRAYJOIN(ARRAYUNIQUE(values),"\n")

I am wondering if there is any way to alphabetize the result output?

If you sort the primary field alphabetically, will the US states be also alphabetized? If so, you can run the batch update block on the linked record field to sort the linked records alphabetically. Then the rollup values should be sorted the same as the linked records.
