You are mistaken.  Did you check the sections I cited?  You seem to
have a fixation with spreading FUD about the specification.

I hope that 4 is a typo.  The code you originally posted works as per
the spec in IE6 (contrary to your previous claims).  If is was broken in
one, it had to be in Mozilla.  Whilst I doubt that, I can't easily test
old versions of it.  You appear to be immune to these facts.

The code you most recently posted shows nothing since if you want to
compare two string numerically it makes sense to convert both explicitly
to numbers.  There's no relation to the previous point about implicit
conversions as far as I can see since, given that you were unaware of
what the language requires, you would not have converted only one.
Anyway, you don't post the code that you say caused problems, only the
"corrected" code which is exactly as I would expect it to look.
