Thanks for pointing that out, I had missed it.

For some reason [no-math] or \@zf at mathfalse do not seem to work in the  
way I expected: they do have an effect on \mathrm for example  
(yielding the same as \textrm with [math] and cmr with [no-math]), but  
not on the math digits which are taken from cmr in both cases.

I must have misunderstood something somewhere. Beats me!
