Right, the current editor's draft is trying to define orientation with
a combination of the script of the character and UTR50 in the
common/inherited/unknown case. It would be simpler to define
'upright-right' in terms of the default orientation in UTR50 for all
codepoints.  That way CSS specs don't need to track script additions
to Unicode and decide whether the scripts are vertical or not.
