I can't give you the full answer because I'm away from my computer.
However, the main problem is that RasMol orignally used the standard
computer-graphics left-handed coordinate system.  This was fixed early
on, but consequently the coordinates are (I think) different those
used by other programs.

The easiest way to get data from rasmol to molscript is to just use
the "write molscript" command in rasmol.  It will create a molscript
file which preserves the current rotation.
