You have been given a lot of good advice. I don't think anyone really enjoys getting tagged, but it is not nearly as bad as being bitten by a rat or mouse (those things HURT!). What I do when having to handle a snake that likes to tag me (my roommates taiwan's) I make a fist and have the back of my hand going to the snake first. Now I have big hands and when I do get tagged there is nothing much for them to hang on to. I find most of my snakes settle down once you have them out of the cage. For now though just leave your little one alone. I would throw a cover over it and/or do like the others have said and put something around the tank so he doesn't feel so stressed. Good luck and keep us posted on how it is going.
