As Rejeesh pointed out this happens with any traditional lipi font. I am 
not aware of what Uniscribe does with it. Meanwhile, if the reph postion 
flag for Malayalam changed to REPH_POS_AFTER_POST from 
REPH_POS_AFTER_MAIN ( in hb-ot-shape-complex-indic.cc ) the problem 
disappears!. But then it is moved even after the post base matra which 
is undesirable, too.
