The problem with the Sage's rulings are two fold in general:
1) He tends to look at a single sentence in a book and make a ruling on it, even though there are other sentences in the books which might have bearing on the subject. He seems to be very literal with regard to the rules and very focussed on single instances of a given rule.
2) If you want to make sure he makes a good ruling, you cannot just ask him a simple question because he might not realize the points of contention that sparked the question. A better way to ask him is to say "Mind Blank states ..., True Strike is a divination spell that states..., so does this clause in MB prevent TS from targetting an MB protected character?". Just asking him if MB stops TS does not ensure that he even reads the spells.
This is one of the reasons he changes his rulings on occassion. People do not give him enough information and expect him to pull out the books and read several different sections on his own. I really doubt he has time to do that every time. If you ask him questions like these without giving him details, expect his answer to possibly change in the future.
