Most likely the error you are experiencing happens exactly because you
run the script as root and the root user doesn't know the X11
authentication cookie. Please note that this is in no way Avahi error,
this happens to all X programs if you call them like that.

There's no reason to run avahi-discover as root. Just run it as normal
user and everything should work fine.

Alternatively open up your X11 display for everyone by entering 
"xhost +" on some (non-root) terminal on your X session.
