I love superclean but I had the same problem with the AOSP clock. So what I've done since the first one is open Rom Manager, click Download Rom, click Sonofskywalker3, then click Desk Clock and download the Stock Desk Clock and let that download.
I don't use rom manager to restart and install anymore because it used to boot me into a different recovery so I then restart into recovery using the button when you hold the power button and install the zip from SD card. It's a little tricky to find but you start in the Clockwork Mod folder. Find the zip for the clock and install it.
Also you may have to disable Voodoo to install, if you're on Voodoo, I know I did.
The clock will take over as your default clock but the AOSP clock will still be there.
Hope this helped!
