Blogger's "Select Blogs to Display" Jumps Around

If you own multiple Blogger blogs, Google has a page that lets you set which of those blogs appear in your profile. An interesting property of that page is that the order of the blogs in the list is not constant. In fact, it seems to be random - every time I press "Save changes", the entries reshuffle themselves. Whether I've checked or unchecked an item doesn't seem to affect the shuffling at all.
