There are no scripts made for this, as I'm aware. But if you have two lists of their appearances (can be generated from a category with Mass Categorization, for example), you would only need to paste two lists in either excel, or this site (I recommend), or any other sortable tables.

E.g.: there are two categories I open Mass Categorization tool, click "add category contents", type both names, copy the list I got and paste it here. As result, there are 10 files that have both categories. The whole action took 2 minutes or less.
