Do not create a third partition or you will not be able to remove the Windows partition using Boot Camp Assistant. Furthermore, you will not be able to manage the Windows partition with Disk Utility either.
Why do you need to make a third partition?

If you're beta testing mountain lion your best bet is to run that on an external disk. Also, you should use the Appleseed discussion forum for questions pertaining to that.

If you prefer to maintain a Windows partition along with two other OS versions, then the only viable solution is to use rEFIt. REFIt is an alternative bootloader that can manage OS X, Windows, and Linux partitions on the same drive. Using it will of course preclude the use of Boot Camp Assistant. But rEFIt is the solution to this issue although I can't speak for its compatibility with Lion or Mountain Lion. Be sure you carefully read the documentation before installing it including how to uninstall it should you need to.
You can use Disk Utility to add a third partition by shrinking the existing OS X partition to make space for the third partition that will sit between the Lion and Windows partitions you now have. I have no clue how this will deal with the invisible Recovery HD partition, but I think it is at the end of the Windows partition.
