Hi,
I am not a specialist, but I use the « btex etex » commands, such as
dotlabel.bot (btex \switchtobodyfont[10pt] \strut $R$ etex, z1)
I just tested with the latest beta, and everything works fine, but not the
\pmatrix construct (I tried also with ${k}\choose{n}$, which works fine too.
I put my test file in which some maths is used in a MetaPost graphic here:

Best regards: OK
