If I knew the answer to that question, I probably would have solved this whole mystery already, and everyone could be off posting on other threads.
And, of course, I would win the door prize!

I think I might be able to answer my own question as to motive. Someone out to discredit Taitz creates an elaborate fraud Obama BC with several tell-tale similarities to another totally unrelated document, the Bomford BC, and gets her to take the bait, knowing that the Obama fraud will be exposed by the discovery of Bomford, the ticking time bomb. Diabolically clever.
