Yes, but say you define base font-sizes in your #mainbody (14px) and
#sidebar (12px) divs and then use percentages for your h1, h2, and h3 tags,
intending that those percentages scale based on the font size set in the div.
Since h1-h3 would come before both mainbody and sidebar in your CSS when
arranged alphabetically, the font percentage sizes would scale based on the
user's default font size rather than those set in the divs, while those for
your #callout div would scale as you intended.
Of course, even methodologies that put all the html tag definitions before
all the classes would run into this sort-order problem.
