>          Issue Type: Bug
>          Components: Core
>         Environment: RHEL 6.3 virtual guest, apache-cassandra-2.0.6-SNAPSHOT-src.tar.gz from build #284 (also tried with 2.0.5 with CASSANDRA-6666 patch custom-applied with same result).

>     create table test4 ( name text, lname text, tc bigint, record text, PRIMARY KEY ((name, lname), tc)) WITH CLUSTERING ORDER BY (tc DESC) AND compaction={'class': 'LeveledCompactionStrategy'};
>     create index test4_index ON test4(lname);
> Populate it with some data and non-zero tc values, then try:
>     select * from test4 where lname='blah' and tc>0 allow filtering;
> And, (0 rows) returned, even though there are rows which should be found.
> When I create the table using CLUSTERING ORDER BY (tc ASC), the above query works. Rows are correctly returned based on the range check.
> Tried various combinations but with descending order on tc nothing works.
