Thanks, Hans!  It seems to work in the latest beta.

The version
in tex/texmf-context/tex/context/fonts/mkiv/type-imp-mathdigits.mkiv is
a typescript.  Here is a simpler version using defintfontfamily and
definefallbackfamily, which doesn't work in the recent beta (but worked
well back in January).


\definefontfamily     [minionmath] [rm] [Minion Pro]
\definefallbackfamily [minionmath] [mm] [dejavusansmono]
[range=digitsextendedarabicindic,offset=digitsnormal]
\definefallbackfamily [minionmath] [mm] [dejavusansmono]
[range=digitsextendedarabicindic,offset=digitsbold,tf=style:bold]
\definefontfamily     [minionmath] [mm] [TeX Gyre Pagella Math]

\startttext

\switchtobodyfont[minionmath]

\startformula
{\tf xyz} xyz {\bf xyz} {\bi xyz}, 2+3, {\bf 2+3}
\stopformula

\stoptext


With beta version 2017.01.17 17:37 it used to work and change the digits
to Indic inside math.  With beta version 2017.04.27 01:00, the digits do
not change to Indic.  However, everything in math changes to
dejavusansmono (bold, because that was the last fallback definition?).

there has been some fixes in the math fallbacks recently so only report issues that fail in the *latest* garden version
