Error returned from SQL Server: Incorrect syntax near: NULLS

Running the TPCR queries has worked previously, I believe even with Teiid from a short while back. Now it's not. This particular query is detailed below.

Transformation text:
SELECT
S_NAME, COUNT AS numwait
FROM
TPCR.SUPPLIER, TPCR.LINEITEM AS l1, TPCR.ORDERS, TPCR.NATION
WHERE
(S_SUPPKEY = L_SUPPKEY) AND (O_ORDERKEY = L_ORDERKEY) AND (O_ORDERSTATUS = 'F') AND (L_RECEIPTDATE > L_COMMITDATE) AND (EXISTS (SELECT

• FROM
  TPCR.LINEITEM AS l2
  WHERE
  (l2.L_ORDERKEY = l1.L_ORDERKEY) AND (l2.L_SUPPKEY <> l1.L_SUPPKEY))) AND (NOT (EXISTS (SELECT

• FROM
  TPCR.LINEITEM AS l3
  WHERE
  (l3.L_ORDERKEY = l1.L_ORDERKEY) AND (l3.L_SUPPKEY <> l1.L_SUPPKEY) AND (l3.L_RECEIPTDATE > l3.L_COMMITDATE)))) AND (S_NATIONKEY = N_NATIONKEY) AND (N_NAME = 'SAUDI ARABIA')
  GROUP BY S_NAME

Query I executed:
select * from vTpcr.Q21 ORDER BY numwait desc, s_name LIMIT 100;

Error I received:

This failed both in the Designer (running the version from 8/31) and Teiid (9/1, running as a server). I'll attach the server log and project to this defect.
