I've been playing with Lion and Mission Control. I'm not sure how I did it, but I seem to have reordered my desktops.
When I open Mission Control, the labels of the desktops at the top of the screen are (from left to right):
Dashboard, Desktop 1, Desktop 2, Desktop 4, Desktop 5, Desktop 3 (in the wrong place!), Desktop 6, Desktop 7, Desktop 8, Desktop 9
How did I relocate 3? And how do I put it back in the right place?

What you can do is this:
Delete the desktops and then recreate the by hovering over them and pressing the red thing in the corner, then looking at the right to make a new desktop.
This is no longer necessary as of Mac OS Lion 10.7.2, see this answer for an easier solution.
