I didn't tell you that:

\definefontfeature
[default]
[script=latn,language=dflt,liga=yes,kern=yes,tlig=yes,onum=yes]

(the important setting is only "onum=yes")

The problem is that that's only a dirty trick that is not supposed to
work and might stop working in the future, so I would rather try not
to rely on it. A better interface for XeTeX typescripts (something
similar to fontspec) is missing heavily.

Concerning your first problem: I have tried patching Xsans definitions with

\definefontfeature
[oldstyle]
[script=latn,language=dflt,liga=yes,kern=yes,tlig=yes,onum=yes]

\starttypescript[Xserif][all][name]
\definefontsynonym [DummyOldStyle]  [name:\typescripttwo]   [features=oldstyle]
%\definefontsynonym [DummyOldStyle]  [name:'\typescripttwo']
[features=oldstyle]
\definefontsynonym [OldStyle]       [DummyOldStyle]
\stoptypescript

\definetypeface[myface][rm][Xserif][Warnock Pro]
\setupbodyfont[myface, 11pt]

\starttext
{\os 123456789}
\stoptext

but I have no idea why it fails.

The alternative fails with
