The current implementation of NULL ordering doesn't work in Oracle. The generated ORDER BY statement causes Oracle to throw OCIError: ORA-00933: SQL command not properly ended.
I believe I've found a DBMS-agnostic way to do this, which I've got in a commit in my fork of this repo: barendt@abe9f42
Once the dust settles from the changes you're working on now, I'll figure out how to get this change incorporated into that and I'll submit a PR.
