I've been looking at this. We do have language support in both OpenType
and Graphite in Scheherazade. However, as I've looked at the
documentation for XeTeX I see no mention of how to choose a language in
Graphite, only in OpenType. So maybe using a language isn't supported in
XeTeX Graphite? If that's the case, then you need to turn on the
specific features required for a particular language. So, if you want to
use Sindhi features you'll have to turn on Sindhi-style Meem,
Sindhi-style Heh, and Sindhi-style Eastern digits.
AFAIK, Scheherazade 1.005 wasn't a Graphite font so I don't understand
what you were seeing there.

Thanks, Khaled. I had wondered about this--which is why I specifically
chose the Graphite renderer in the font selection. (According to the
"Font Features for Scheherazade 2.000" on the SIL web site, both the
language selection and the meem/heh shaping should work in either
OpenType or Graphite. Rohingya is available as a language selection
only in Graphite--but fontspec doesn't recognize the language.)
Is there a reason a hybrid font wouldn't work properly if a specific
rendering technology is chosen? (Specifically selecting the renderer
worked great in solving my small-caps problem.)

It seems that Scheherazade ? 1.900 is a hybrid OpenType/Graphite font,
so this is the same issue as:
http://tug.org/pipermail/xetex/2013-June/024530.html
(This will be fixed in next year's version of XeTeX, the workaround in
the above link can be used in the meantime.)
