If you look at the git history for OVS, you'll see that there actually is a v1.0.2 tag.  I don't believe what's in XCP exactly matches this, but it should be fairly close.  The Xen folks maintain their own version of OVS, which is typically a commit at some point in our development process and then bug-fix patches applied on top.  We're now providing more long-term stable release branches of OVS and coordinating with the Xen guys so that we can hopefully get release schedules more in sync going forward.

OVS only supports OpenFlow 1.0.  That is specifying a range of minimum and maximum versions supported by that utility, which is only 1.0.
