I think you are getting confused between two different ranks.

Your job can rank machines. You do this by setting "Rank = " in your submit 
file. If you do this, you will see the rank when you do a condor_q -l.

Your machines can rank jobs. You do this by setting the RANK in your 
condor_config file. If you do this, you will see the rank when you do a 
condor_status -l.

You changed the machines' ranking of jobs, so it will not show up in 
condor_q. It will show up in condor_status -l. When you do, you should see 
two things:

1) Your rank expression
rank = ...

2) The current rank value for a job that is running. (If there is a job running
current_rank = ...

=?= has worked well for us--we use it regularly.

If Workgroup has not been set, then (Workgroup =?= "7") will be zero.

Note that if Workgroup hasn't been set, you might get strange results. Your 
expression is:

(Workgroup =?= "7") * 100000 + (TARGET.Workgroup =?= "7") * 10000 + 1

ClassAds in the current version of Condor are a bit weird.

a) for the "Workgroup", it will look first in the machine, and second in 
the job.

b) For TARGET.Workgroup, it will look first in the job, then the machine. 
You would think that it would only look in the job, but it doesn't. This is 
wonky, but it's the case.

I hope this helps.
