I did some further experimentation, hoping using dimexp calculations would help. But either I am doing somthing wrong or I do not understand the innards of bodyfont switching well enough. The example program seems to have accessed a 30 pt font (see the log file) but did not typeset in it, the dimexpr does evaluates to 30 pt. Where am I at fault?

This is but a partial solution in my case, for two reasons:
1. \textstyle=\small gives few control, I tried textstyle=5pt without result
2. the setup cannot be placed inside \startuseMPgraphic, where I need it most.
I skimmed through meta-ini.mkiv, but did not find a solution.
It is however quite possible things cannot be done other than by putting a
fontchange inside each label.

What is the simplest way to change the size of fonts in labels drawn in
MetaPost?
Probably a font switch directly in the label:
label("\small foobar", origin);
\switchtobodyfont[size] can be done in \startMPenvironment and inside each
label.
Better use setupMPinstance:
\setupMPinstance
[metafun]
[textstyle=\small]
