Tags not alphabetical when using tagmenu_format=select

Hi!
Thank you for this plugin!! When I am displaying the tags in a list or with checkboxes, they sort alphabetically. But when I display them in a select box by using tagmenu_format=select, they are not sorted alphabetically.

My site is a current work in progress, but you can see the behavior I’m referring to here: http://www.thewelloiledlife.com/infographics. Thanks!
