The main difficulty is not the style settings for each of these fonts
but the \text \script \scripscript scheme of sizes iself. Note:

-- The numerator and denomiator of fractions come out in a smaller
size than the normal one, approximately what would be the \smallsize
of LaTeX.
-- Fractions within fractions appear at same size that the main fraction.
-- Exponents are set in a size that would be the script size of the
fractions text, and the same size is used bor both text-size basis and
fraction-size basis.
-- There is not a subsubscript size; i. e., all levels of
sub/superindexes are displayed at the same size.

Thus, the size of fractions is not textsize neither scriptsize.
