I have decided to run a ground wire along side the SE cable. As Don said there is no way to force the customer to change to a 4 wire cable. The Code gets close to this situation when it states it is permitted to run the equipment bonding jumper outside of the raceway for up to 6 feet per Article 250-102(e) but this situation is not a bonding jumper. Article 250-24((a)(5) shows the sub panel, as wired, to not be in compliance. Article 250-142(b) is of no help because of the building being attached. So leaving the sub panel as it is would be further from compliance than running the single conductor along side the SE cable.
Thanks for the comments.
