I recently came across Netdot which can find every occurrence of VLAN X 
across multiple switch vendors and models. It currently can't produce a 
script, but it's perl so I can't imagine it'd be too hard. It also gathers 
CDP/LLDP data and automagically maps the topology but I don't think it 
will note discrepancies. It will generate a (very messy) graph of VLANs 
between switches. Again, perl.
