Change [VCE_Ifvariable] to [VCE_Ifvalue], change "Cl:score" to "<var:cl:score>", and although this is not required for simple, single Ifvariable VCE events, I'd suggest you use out a range at the end "1 4", no quotes, no dash, just the number of the first event and the number of the last event, separated by a space.

I HAVE NO IDEA! *Ubercharge ready*
