ACL for webOS 1.2.0 is fully upgradable to the next versions (like the newer one 188.8.131.52)
Just install it over the other one (without uninstalling), reboot and wait few minutes to have all apps restored after the reboot.
Meanwhile about the 0.60 and the 1.0.1 you may would like to doctor to be sure everything would be properly installed. Anyway other users have decided to try without doctoring and some of them (following their words) reported that all seems ok, so it's up to you! I personally have doctored.
Also, Cuspie is working on a script to get the 0.60 and the 1.0.1 removed completely, so in case you don't want to doctor, and you don't want either to risk with upgrading to 1.2.x, you may wait for his script.
