Generating a Notify or Autoreply action from inside User Define in a scrip

Is is possible to generate a Notify or Autoreply as part of a User
Defined action in a scrip?

If I try to string together multiple scrips on the same condition (On
Create) then the scrip with the User Defined action is processed last.

I would like the scrip with the User Define action to be processed first
or include the Notification in the User Defined action rather than using
multiple scrips.

Thank You
Robert
