Ah I see,
Unfortunately, I don't think this is easily doable then. I think you'd need to do the mapping yourself. That ID can be found in the UI. If you go to the audiences table in the shared library and click on an audience you can see its "List ID" in the "Summary" panel at the top. One of your audiences will have a List ID of 5776946. I don't know how many audiences you have, but if the number is small, you could hard-code this mapping somewhere in your script and convert the Criteria strings into meaningful names.
I'll take a look and see if we can convert these strings automatically, but not sure how long that will take. I think it makes sense for us to do it since if you download this same report from the UI, it prints out the name of the audience rather than "boomuserlist::LIST_ID".
Cheers,
