Although the work to use the zsets order in the sort command works for the basic case. I had a need to be able to use the full capabilities of the ZRANGEBYSCORE and ZREVRANGEBYSCORE commands while fetching associated keys.
I basically exposed the lookupKeyByPattern and createSortOperation commands from sort.c and reused the same based code as sort.c within the genericZrangebyscore function. I also added a few simple test cases that basically match the sort GET test cases.
Added GET to zrangebyscore commands.
Add today about EPSILON lowering.
