How Can I do the CSS-Content-Order-Flip for Better SEO in ATA?

I noticed that content early in the code of the page is indexed better and more pervasively than others.

-Which has led to some equally hilarious, atrocious and saddening SEO on this ATA blog and others previous.

*So My Question is This: How can I adjust ATA's settings so that I can put the Center Content Column First in the code of a 3-column page, so that's what Google reads first+most importantly, -with the sidebars code following after,

-In the style of what this guy did here: http://matthewjamestaylor.com/blog/perfect-3-column.htm

*Note: The key problem being that ATA uses tables w/divs inside, instead of All Divs.

Thank You!

Title, H1, Url, description, categories, tags, all point to their subject matter; -but the GOOG still decides they've just GOT to be about, "December"
-lulz! I am baffled. )
