While I don't have the documentation at my fingertips, I believe that
FindScriptRun uses the current script system (according to
thePort^.txFont) to parse the text, which it then splits into script
runs.

So the text you pass it has to be all of the same script.  This leads
one to wonder as to the utility of FindScriptRun.

The solution to this puzzle lies in the fact that some (most?) script
systems are two--two--two scripts in one:  they contain roman
characters as well as the native ones.  FindScriptRun lets you find
the roman characters that don't belong.
