Mark,

Nice catch.

There is support for Outcomes in Sakai 2.8 but not the LTI 1.1 outcomes.   Thanks for jogging my memory.

I created a little set of "extensions" to LTI 1.0 that I implemented in Sakai 2.8 before LTI 1.1 was finished.   The Sakai 2.8 outcomes look quite different than the Sakai 2.9 / LTI 1.1 outcomes.   But the data model is the same and a tool can easily support both approaches because there are signals in the POST data as to which version of the service is supported.

The documentation for those extensions has never been made public because they were an IMS internal document that will not ever be published.   I have documentation I can share privately and even some sample code for the 2.8 outcomes.  I have to dig it up.

While the 2.8 (non-standard) extensions are not exactly the same as LTI 1.1 - they are still far better than writing a whole new web service.

If someone really wants to build grade return that works for both 2.8 and 2.9, I am happy to help - some info will have to be sent off-line until I can write new documentation that is suitable for public distribution.
