The code is a little strange -- I hadn't looked at it before. The real work is happening in residue.cpp::GetAtomIDNumber() which processes the properties based on the atom labels. I don't know nucleic acids all that well, but if you send me some sample files with a few annotations, I can certainly patch GetAtomIDNumber. It looks like backbone IDs are supposed to be between 7-18 from reading the code.
