If you need a custom Fixlet/Task to fulfill your exact needs, then I would second Tim Rice’s statement about engaging IBM Professional Services. They do provide custom content authoring, and contracts to support your own efforts at authoring content.
This forum is mostly users helping each other. Josh posted a great place to start. If the relevance he posted isn’t returning the true/false that you expect, then it’s really incumbent upon you to try to understand why that is occurring.
The first place to start would be to take apart Josh’s relevance. If the dacl doesn’t match what you expect (true/false), then find out what the dacl actually is, by removing the boolean comparison and just displaying the string result:
q: dacl of security descriptor of folder (expand environment string of “%25SystemRoot%25\System32\drivers”) as string
