It seems to me that autofill take the first address from the Contacts, in other words the oldest one. I have not figured out how to change.
Seen advices to use minus but it removes the address for good, and ticking "sharing box" have no impact.
Only way I have fixed this is manually delete earlier created addresses and type them in again into your contact card.MacBook Pro, OS X Mountain Lion (10.8.2)
