Imposible authorization of two applications with same creator

I’ve found a strange Mac OS X behavior.
I’dont know if it’s a bug or a feature.

In Parent Control, you can’t auhorize two applicantions wih same creator,
If you try to authorize two AppleScript compiled scripts, you get an error message.
The AppleScript compiled applications have aplt creator.
I was trying to set as startup applications two AppleScript applications for an user with limitations.
So, first, I must to authorize using those applications.
I was possible only after changing the creator of one of them.
