Well, combining characters are supposed to follow their base characters,

The idea is that there might be more than one way of getting an encoding to
do something. Despite the fact that Tibetan has explicitly coded subjoins,
it would be possible to implement Tibetan with a virama model. It is
considered wasteful to promote that kind of thing. The text in the Unicode
manual tries to give guidance on such matters.
