Perhaps using ifThenElse? For example:

NORMAL_PRE_JOB_RANK = 1000000 - 100 * Memory - $(SWEEP_DIFF)
PARALLEL_PRE_JOB_RANK =  1000000000
NEGOTIATOR_PRE_JOB_RANK = ifThenElse( (Target.JobUniverse==11),
$(PARALLEL_PRE_JOB_RANK), $(NORMAL_PRE_JOB_RANK) )

The default condor_config has things like:

VANILLA         = 5
IsVanilla       = (TARGET.JobUniverse == $(VANILLA))

So you could add

PARALLEL = 11
IsParallel  = (TARGET.JobUniverse == $(PARALLEL))

And then use $(IsParalleL) in other expressions (e.g. N_P_J_R)
