Thanks for your answer, Ralf.

The problem here is that the font has these locl substitutions defined
for the Latin script and there for the default language (that is,
latin{dflt}. I don't know if XeTeX should apply these substitutions when
 defining \foreignlanguage{greek} and selecting polunikogreek as an
option in babel.

I'm not sure whether it is possible to define these locl substitutions
for the math, since it is only a baseline script.

Probably the correct tag for this GSUB routines would be mgrk
instead of locl. I will report this to the font developer).
