Does the above indeed work? AFAIK the following is needed:

vardef LATEX primary s =
  write "%&latex" to "mptextmp.mp";
  write "verbatimtex \documentclass{article}" to "mptextmp.mp";
  write "\begin{document} etex" to "mptextmp.mp";
  write "btex "&s&" etex" to "mptextmp.mp";
  write EOF to "mptextmp.mp";
  scantokens "input mptextmp"
enddef;
% ... could also be put into some file LATEX.mp
% and then do: input LATEX;

beginfig(1)
label.rt(LATEX("\tiny little label"), (0, 0));
label.rt(LATEX("\bfseries fat label"), (0, 10mm));
endfig;
end
