I think it would be nice to do a regexp_replace to fix these issues in the database for existing installs. I don't know if that is an acceptable practice though. If an org was already using the event, and already fixed the typo, then it should have no effect.
It might be a surprise if someone is using the selfcheck receipts, and the zip code starts showing up now. But I don't know if that would be considered good or bad.
