Components.utils.evanInSandbox accepts a string JS version to use during evaluation but there is no way to just have it use the latest JS version, you either have to use a fixed version or whatever version the caller is using. I'd suggest we just need to add something like "Latest" to this mapping: http://mxr.mozilla.org/mozilla-central/source/js/src/jsapi.cpp#1056

JS versions are dead. The version argument of evalInSandbox is unused; it's only left there for backwards compat.
