Thanks, Hraban.That’s a helpful start

 I guess the challenge now is to get STIX Two Math to use the oldstyle
numerals in STIX Two Text (by adapting code that Wolgang gave me for using
 oldstyle numerals with TexGyre Math). When I ran

mtxrun --script fonts --list --info stixtwotext, I got

mtx-fonts       |   onum     cyrl     dflt

mtx-fonts       |            dflt     dflt

mtx-fonts       |            grek     dflt

mtx-fonts       |            latn     dflt rom trk

Sadly, I have no idea what this means or how it might help in identifying
the Unicode range of the oldstyle numerals in STIX Two Text. And that is
something I need to take advantage of Wolfgang’s code.
