Appscript doesn't provide an API for calling user-defined  
subroutines. You need to drop into aem and use raw AE codes to do that.

The simplest thing would probably be to call your applet's user- 
defined subroutines via aem:

#!/usr/local/bin/python

from aem import *

playRec = Application(findapp.byname('playRec'))

playRec.event('ascrpsbr', {'snam': 'initRecList', '----':  
[False]}).send()
recList = playRec.event('ascrpsbr', {'snam': 'listRecDict', '----':  
[]}).send()


If you really want to add a dictionary, assuming you've saved your  
applet as a bundle, use sdp to convert your sdef to a .r file, then  
use Rez to append it to your applet's applet.rsrc file:

sdp -fa playRec.sdef
Rez playRec.r -a -o applet.rsrc -useDF


You'll need to define your applet's handlers using the raw AE codes  
given in your dictionary, of course, e.g.

on «event PRecIntL» arg
    ...
end «event PRecILst»

<command name="init rec list" code="PRecIntL" description="">
	<direct-parameter type="boolean" description=""/>
</command>
