Thanks all! I did a ghetto workaround to make this work with Bartender - I just had the script quit Bartender at the beginning and then start it again at the end. It actually is surprisingly fast, so it seems like it will work for me until someone smart comes up with a real fix.
(I adapted tabacitu's version because I thought it was faster.) Thank you paulw - I leave yours running too so I can tell from the Alfred results whether DND is off or on. But then I run tabacitu's version to toggle it.
try
tell application "Bartender 2"
quit
end tell
end try
tell application "System Events"
set toggled to false
option key down
delay 0.1
try
click menu bar item "Notification Center" of menu bar 2 of application process "SystemUIServer"
set toggled to true
end try
if not toggled then
try
click menu bar item 1 of menu bar 2 of application process "SystemUIServer"
end try
end if
option key up
end tell
tell application "Bartender 2"
activate
end tell
