No idea, but having suffered from mysterious Windows font installation
issues before (not with XeTeX), I’ve learned to delete the existing
font(s) before installing a new version.

No idea, here I get no smallcaps at all on the first line, and proper
smallcaps on the second one, so it seems another manifestation of the
confusion caused by installing multiple font versions. May be we should
give priority to fonts with higher version numbers in case of
duplicates, though I’m not sure if this would help the Windows issue.

Can you attach the XDV files from your example, by using --no-pdf option
(which reminds me to finish XDV support in dviasm and publish it so
people can examine XDV files themselves).

Yes (fontspec fails because it first checks if the font supports the
given feature and if not it removes it from font definition, and since
it is looking for OpenType features it finds none when Graphite shaper
is used).
