Are you sure the attached patch is up-to-date with your work?
I get a small change clef in the fifth line, see attachment.

Sorry - can't help on that. But generally, wouldn't it be better to 
store the
offsets in an alist, so that each (glyph . direction) pair has an offset
number?
You'll have to take clefs.G_change and the likes into account, too, so the
if-else-constructs will be rather clumsy.

Just my 2 ct.
