Adobe Reader has a surprising number of applications that will trigger a reboot if they are running during the installation. /norestart doesn't stop the 3010 exit code, it just stops the installer itself from prompting for a restart. When Software Center gets the 3010 exit code, it handles it as defined in Client Settings.
Two options you can do are to change the reboot behavior or change the exit codes in the deployment type settings to set 3010 to a non reboot code.
