I don't believe so-- a group of radio buttons is conceptually the same
as an option menu or a single-selection list, which you also tab into,
use the arrow keys to make a selection, and tab out of again.  If you
had Tab moving through each individual radio button in turn, we'd also
have to change the proposed functionality where focusing a radio button
also selects it, which I think would cause unnecessary extra effort for
the keyboard user.

(Java and Windows also both see fit to implement it this way, IIRC, so
it's probably not unreasonable).
