Well, word 1 to 3 of theObjectRef gives:

field id 1072

since theObjectRef looks something like:

field id 1072 of group id 1052 of group id 1057 of group id 1004 of  
card id 1009 of stack "PDdata" of stack "/Users/pmbrig/Documents/ 
Revolution stacks/ PtData-rev/ Psychopharmica.rev"

but I want to extract the short name of group id 1004, the last one  
before the card. I could have parsed the long id by replacing " of "  
with comma, finding the itemoffset of "card id" and subtracting 1, but  
for whatever reason at the time* I chose a recursive function, and it  
works fine.
