Headings not alphabetized?

Love the plugin–for some reason, while the tags are alphabetized within the heading, the headings are showing up not alphabetized for me.

Here’s what I’m talking about: http://yesterdish.com/tag-index/

Here’s what’s generating that result:
[mctagmap columns=”5″ hide=”no” show_empty=”yes” tag_count=”yes” descriptions=”yes” width=”140″ equal=”no” basic=”no” basic_heading=”no” show_navigation=”yes”]

I’m guessing this is something semi-dumb and obvious that I’m forgetting and hoping someone has a thought on how to fix it? Thanks!
