Apply table style based on cell content

I am using InDesign 5 and am on a Mac, OS 10.8.5.

Does anyone know how to apply a table style based on text contents found in a cell in javascript?

I need to search the document and change every table style to "verbatim orange LONG" if the text "HS:" appear in the header row.

I've been playing with the scripts found in the following 3 threads, but can't get it to apply a table style.

Thanks!
