I can suggest CSS way to accomplish this. I checked that it works with
firefox, but not sure for other browsers.

Minimal Org example:
#+BEGIN_SRC org

#+TITLE: An example
  ,#+OPTIONS: num:nil
  ,#+HTML_HEAD_EXTRA: <link rel="stylesheet" type="text/css" href="ex.css"/>

  ,* This is title on top level

  Text for document body.

  ,** Title for subtop level

  Text for body of subtop level.

  ,* This is title of next top level heading

  Text text text.

  ,** Title of second order

  Text text text.
#+END_SRC

Additional CSS
#+BEGIN_SRC css

body {
  counter-reset: level;
}
#table-of-contents > h2:before {
  content: normal;
  counter-increment: level;
}
h2:before {
  content: counter(level, upper-latin) "  ";
  counter-increment: level;
}
h2 {
  counter-reset: sublevel;
}
h3:before {
  content: counter(level, upper-latin) "." counter(sublevel) "  ";
  counter-increment: sublevel;
}
#+END_SRC

Note, that use have to turn off 'automatic' numbering when exporting
from Org, this is because export routine inserts numbers 'by-hand' don't
relying on CSS (imho, not bad because there are browsers that don't
support CSS, but it would be great to have option to switch this
on/off).

Second, in example only headings of two levels (top, subtop) will have
desired format.
