No, against it would not be any more or less proper than without
calling .valueOf() or .getTime(). Automatic type conversion does the job,
see ECMAScript 3 Edition 3 Final, section 11.8 (one wonders how many times
Matt must be told this). And it works perfectly fine in Mozilla/4.8 [en]
(X11; U; Linux 2.6.15.6-20060314.201202+0100 i686).

However,

  args.isValid = (useDobDate < useDodDate);

is more efficient.
