Meta tags, SEO, link rel stuff all out of order

Perhaps it doesn't matter, and perhaps this has been answered already (I did a search but didn't find a thread on precisely this): in my header source code, some meta tags appear right up at the top, but others are way down almost at the end of the header section, separated by large areas of SEO code (I'm using All in One SEO Pack) and by very large areas of plugin JS and other plugin stuff. Aside from possibly adding to page-load time, isn't it better from an SEO standpoint to have all the meta tags together at the top?

I've added only two meta tags in the HTML inserts area: , and these are at the very end of the header area right before the header closing code.

Is there any way to tidy up the header area?
