IIRC arithmetic evaluation $(()) and process execution using $() were not in
the original Bourne shell, they are POSIX features (that came first from the
Korn shell I think).

I wouldn't expect it to, that's what I had to add to reproduce your problem.
However, I think if you add
let g:is_posix = 1
as well you'll be good, without adding bash or ksh support. I suspect you've
really got an Almquist shell. Note that vim's help in syntax.txt says
posix: (using this is the same as setting is_kornshell to 1)
let g:is_posix = 1
but my reading of syntax/sh.vim suggests this is no longer quite true.
