Don't see why it is not working ? Philz touch is working right ?
Latest philz touch recovery
Flashing philz zip file won't change anything. It's made as a zip but can be used by people who have s-off.
Boot into philz recovery, go to mounts & storage and tap the last option in that list (mount as mass storage)
Then wait until it comes up as a usb diskdrive in windows.
Copy the rom.zip to the sdcard and then make a full wipe in recovery.
Wipe cache partition
Wipe dalvik cache
Mounts & storage - format cache,data,system
Then install the rom.zip and reboot back to the bootloader and flash the boot.img from the rom.zip
Should be done then. Custom roms are rooted already.
If you want a rooted stock rom you have to restore your stock nandroid backup and install su.zip over the stock rom.
Installing a superuser script before installing a rom won't work.
You do not root a phone but only it's software !
