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?).
