Jeff, I'm guessing that the document your AHJ saw or is referring to is here, and might help you prepare for the meeting with the AHJ:
http://www.ul.com/global/documents/corporate/aboutul/publications/newsletters/electricalconnections/april10.pdf I got wind of this document from John Wiles, and he has always been pretty adamant about panels being listed for a supply side tap, which they usually aren't, especially if it is a meter/main combination (or an old Zinsco). Good luck, and let us know how it goes.
