Silly question, but speaking of Inquisitor Coteaz, didn't he have a rule to make everything Inquisition scoring units? What's the point of that if "all units in Codex: Inquisition are scoring units"? Did I miss a Codex update or did they just buff Inquisition overall a bit with this?
In this edition, almost everything is a scoring unit. The rule that you are thinking of comes from teh previous entry in Codex: GK, where Coteaz was lord of the 6th Ed Inquisitorial army. Under 7th, that's no longer relevant.
