Anyone know how to alphabetize the list of purchased apps?

My list of purchases in the app store is growing, and it's getting to the point where the default sort order by purchase date isn't cutting it any more. The old standard of clicking on column headings to sort lists doesn't work in the App Store window, and it's pretty lame to have to read through the whole list to find the one app I want to re-download or add to one of my other computers.

I'm hoping some clever soul has a workaround they're willing to share -- thanks!
