Tag order?

/Polls is going to be adding tags to our posts so that people can filter for just the topics they want to see polls about.

I'm sure this has come up already, but is there a way to sort or re-arrange the tags for posts in the Dashboard? I can't find a control anywhere, and I'm not able to drag/drop them. If I wanted them alphabetical, they have to be re-entered by hand each time I add a new one, which is quite time consuming for /Polls because we're going to have a lot of tags.
