Since HTML does not convey the primary script of a document
(only the primary directionality), it's unlikely that CSS
can automatically choose the correct baseline per script
even if we had such a mapping table. So probably authors
will have to indicate the correct baseline manually. Of
course, I can't predict accurately what will happen when
that module is once again actively worked on. :) But last
time I looked at the issue that was my conclusion.
If you can give feedback on Indic and/or Southeast Asian
typesetting issues, there are a number of them in CSS3 Text:

Spacing and justification suffer the most from lack of
feedback... see particularly
http://dev.w3.org/csswg/css3-text/#script-groups
http://dev.w3.org/csswg/css3-text/#text-justify
http://dev.w3.org/csswg/css3-text/#letter-spacing
