OK, now I got it. (I might have found out myself using condor_q -long.)
Here's an example:
# condor_q -long 385204.349 | grep -i slotid
Requirements = ((SlotID == 1)) && (Arch == "X86_64") && (OpSys == "LINUX") && ...
RemoteSlotID = 1
The existence of RemoteSlotID (and other Remote.* attributes) shows that the
job is already running...

You want to say 'Better use regexp(".*slotid.=.*", Requirements, "ix")'?
At least that would cope with lower/upper case, white space, and ==/!=,
and at the moment I don't fear false positives.
I'm going for
START = (regexp(".*slotid.=.*", Requirements, "ix") == False)
