FWIW the Texinfo Manual says about @math:

  The '@sub' and '@sup' commands described in the previous section
  produce subscripts and superscripts in HTML output as well as TeX; the
  plain TeX characters '_' and '^' for subscripts and superscripts are
  recognized by TeX inside '@math', but do nothing special in HTML or
  other output formats.

Maybe that would be an even better option?
