(Oh, and I know that's the stateside terminology, just wondering why the export is different)
bug tag because I had to pick one.
The Résumé export was conceived as a summary of your profile (formerly referred to as your CV) in which you only include information specific to the position you are applying to and to be used as something you could attach to an email, instead of asking them to visit our website to see your info.
Exported Résumés were designed to be an artifact you could pass around until we convince everyone that the canonical place to find out all about your techie prowess is by visiting your Careers 2.0 profile (no timeline on that yet however).
If the name is all that matters, you could write a script to change Résumé to CV everywhere on that page and then post it on http://stackapps.com/?tab=scripts and use it when applying to jobs to show how good you are at making awesome things.
