Ulrike, thanks a lot for keeping asking questions on this and Philipp
I have figured experimentally that I could use (at least in some cases,
and after math fonts are initialized which in LaTeX seems to mean
one needs to enter math mode at least once before)
for example creating this \fontname:
which is then experimentally observed to obey the second mode specifier
and thus does display lining figures in math mode.
