Is there any penalty for disobeying an order? I once radioed a contact report for a big, fat, juicy troop transport convoy and received a reply telling me to "break off contact and RTB at your discretion". I decided the "at your discretion part" applied to both sides of the "and" and sank a Conte Verde liner. Would that have "dinged" my score?

AFAIK, there is no penalty (or bonus) for bringing back unused fish. There probably should be a penalty for excessive use, as real-life skippers were severely criticized for using too many, at least until the torpedo shortage was over.

As Armistead says, there is a point system where points are given for tasks, or sinking ships, but there are no penalties. The only exception I know of is a penalty for sinking friendly or neutral ships.
I guess there is a penalty for having your boat shot up, or badly damaged.
