does it matter at all what order the or or tags are in in the
It is usually recommended to have the tag as lower down the page as possible (not in the head but in the body).
Other than that, I don't think it makes much of a difference because the body cannot be parsed unless you have the section completely loaded. And, you want your tag to be in the head as you want your styling to occur as the browser renders your page and not after that!
