Kevin,

Script the handler to derive <instance name> & <method> from a custom 
property or global variable which is set when the clone is created:

on createInstance
    global instanceAndMethod
   ...
   clone control x
   put myInstance&"."&myMethod into instanceAndMethod
end createInstance

in the backScript

   global instanceAndMethod
   get offset(".", instanceAndMethod)
   put char 1 to (it-1) of instanceAndMethod into theInstance
   put char (it+1) to -1 of instanceAndMethod into theMethod

If instanceAndMethod is specific to the control with focus, set the 
clone's instanceAndMethod property instead of using a global.

on createInstance
   ...
   clone control x
   get word 3 of it
   set the instanceAndMethod of control id it to myInstance&"."&myMethod
end createInstance

in the backScript

   get the instanceAndMethod of the target
   put char 1 to (it-1) of instanceAndMethod into theInstance
   put char (it+1) to -1 of instanceAndMethod into theMethod

These techniques require no changes to any script when the control is cloned.
