The option "Allow guests to log in to this computer" is stored as "GuestEnabled" key in /Library/Preferences/com.apple.loginwindow.plist

You can change it by using defaults command with root permission, tested on MountainLion 10.8.4

Read

sudo defaults read /Library/Preferences/com.apple.loginwindow GuestEnabled
#1 -> Enabled, 0 -> Disabled

Write

sudo defaults write /Library/Preferences/com.apple.loginwindow GuestEnabled -bool YES|NO
