How can I pause growl notifications via Terminal/Shell?

Question

I was wondering if there was a way I could pause (hide) growl notifications from the command line? Failing that, is there a way to do this with an AppleScript?

The following should work with support for assistive devices enabled, unfortunately, it doesn't for me. But on my machine, even the regular menu item fails to stop Growl…

tell application "System Preferences"
    set current pane to pane id "com.growl.prefpanel"
    tell application "System Events"
        tell process "System Preferences"
            tell window "Growl"
                click radio button "General" of tab group 1
                click button "Stop Growl" of tab group 1
            end tell
        end tell
    end tell
    quit
end tell
