FWIW, I don't see anything wrong per se with using skos:prefLabel to label an instance of skos:ConceptScheme. We deliberately defined the labelling properties skos:prefLabel, skos:altLabel and skos:hiddenLabel to be annotation properties, so you can use them to label anything you like (including owl:Classes). Having said that, I think I would vote for best practice for instances of skos:ConceptScheme being to provide one dc:title for each language. Just because most documentation and examples out there do so already (see, e.g., the SKOS primer [1]).
