InDesign CS3: Batch Print Booklet(s)?

I have multiple documents that need to be printed using “Print Booklet…” and a specific print preset in InDesign CS3. I have found a script that shows one how to batch print multiple documents, but I couldn’t figure out how to convert it to use the “Print Booklet…” option. Does anyone have a solution?

Does anyone know if more recent versions of InDesign have more functionality for handling multiple documents?

Thank you.
