Partitions can not be transposed. There are several good Windows programs that can do this in Windows (partition managers) by copying and moving, resizing, however, I am not aware of anything that can do the same for OS X.

It's probably best to backup what you have, boot the machine with your install media, remove the partitions, erase the drive, and start over.

Partition #1 is always going to be your EFI partition or MBR; Partition #2 will be your Lion boot or startup partition; Partition #3 will be hidden and is the Lion Recovery partition; and finally Partition #4 and thereafter can be whatever you desire.

If you wish, you can install an older version of OS X in any partition that follows the Lion Recovery partition.
