Re: eating mouse tail first
Mine eat it from the tail first sometimes. Maybe he struck it from the back and couldn't find the head. Usually when mine eat it from the back it's time to move up in size on rats though.

All snakes feed differently. My snake has never struck a mouse other than right on the nose every single time. As long as hes not having difficulty swallowing it backwards then everything is fine.

They do eat things weird from time to time, it's nothing to worry about. :)
Now that he is eating, the next meal should be okay to be a normal sized prey item. I think what other posters were trying to point out was that it is more common for a ball python to refuse to eat a meal that is too small than they are to keep rejecting an appropriate sized meal. It may be that the lady was offering him meals that were too small for quite some time.
