I only know the spine and hand tag points, maybe a different spot will fix it. The original script used the left hand, but when ever anyone with a rifle reloaded ( the weapon shifts hands for reloads ) they would lose their weapon.
Is'nt Bip01 just for that model? Have you tryed "tag_back" or "tag_spine"? Also try more numbers at the end. It may use pitch, yaw, and roll. Or it may be using X, Y, Z from the center of the model.
I completely stumbled on this while randomly clicking on files out of frustration - a list of attach points for the players ( if someone else already knows about these - sry it's new to me )
