Had the forger consistently used any of the styles of ordinals he used, it would be plausible he was trying to get away with faking these documents. But if a forger noticed the auto-superscripting and didn't like it, why didn't he kill it everyplace it appeared or--failing that--why didn't he at least settle on one or the other means of preventing it? If the forger weren't concerned about such details, he would have simply let Word auto-superscript when it felt like it. That someone would go through the trouble of killing some but not all such things is a clear sign to me that the person wanted to write "I AM AN MS-WORD FAKE" all over the document.
The forger was not necessarily trying to hide the superscript, he or she may have belatedly realized that 111 needed a th after it (when you have already typed past the area, it seems WORD doesn't automatically superscript the th for you).
Perhaps the forger was just someone who shared the same dismal competence as the CBS "journalists".
