No need to change the source code, HTCondor already supports adding 
custom job (and machine) attributes.  These custom attributes can then 
be viewed with tools like condor_q and even used in scheduling 
expressions (like START, PREEMPT, etc).
Lets says you want to add a custom job attribute "department".  In your 
submit file, insert a new custom attribute via pre-pending a "+" 
character, i.e.
exectuable = foo
universe = vanilla
+department = "Sales"
queue

Then you can view the "department" attribute via condor_q.  You will 
want to use either the "-l" (to view all job attributes), or "-format" 
or "-autoformat" (to view a list of specific attributes) command-line 
arguments arguments to condor_q.  Take a look at this URL for ideas:

Hope the above helps,
Todd
