Since mapserver does nothing with the text except to pass it to fribidi 
and then it renders the fribidi text using freetype, I suspect you need 
to ask this question on the fribidi list.

There was alos a thead a while back that might shead some light on this 
on this in spite of the fact this this thread was about rendering Hindi
