The W3C Editors' Draft has just been updated (27 May 2013):
<http://dev.w3.org/csswg/cssom-view/>

Note that the pageYOffset attribute (which actually returns the same 
value returned by the scrollY attribute) is just one item among many 
others of that document. AFAIC pageYOffset hasn't changed since the 
latest version of the Working Draft.

Nowadays, pageYOffset is widely supported by *all* major web browsers 
(IE9+, FF3+, Safari 4+, Chrome 4+, Opera 10+) since the Working Draft 
was produced by the W3C's CSS Working Group (people from Microsoft, 
Google, Mozilla, Opera, Apple, Adobe, W3C Staff, HP, Intel, etc., even 
from jQuery Foundation - sorry to let you know that.)
<http://www.w3.org/Style/CSS/members>

Therefore, going back to the OP's code, I cannot see any reason to not 
test for window.pageYOffset before testing for the MSIE proprietary 
scrollTop.
