You need to enable OpenFlow13 support with ovs-vsctl, and then tell
ovs-ofctl to use OpenFlow13 too (with "-O openflow13").  The FAQ has
some information.

Q: What versions of OpenFlow does Open vSwitch support?

A: Open vSwitch 1.9 and earlier support only OpenFlow 1.0 (plus
   extensions that bring in many of the features from later versions
   of OpenFlow).

   Open vSwitch versions 1.10 and later will have experimental support
   for OpenFlow 1.2 and 1.3.  On these versions of Open vSwitch, the
   following command enables OpenFlow 1.0, 1.2, and 1.3 on bridge br0:

       ovs-vsctl set bridge br0 protocols=OpenFlow10,OpenFlow12,OpenFlow13

   Support for OpenFlow 1.1 is incomplete enough that it cannot yet be
   enabled, even experimentally.

   Support for OpenFlow 1.2 and 1.3 is still incomplete.  Work to be
   done is tracked in OPENFLOW-1.1+ in the Open vSwitch source tree
   (also via http://openvswitch.org/development/openflow-1-x-plan/).
   When support for a given OpenFlow version is solidly implemented,
   Open vSwitch will enable that version by default.
