something like (not tested; watch line wraps)

put extractHandlerFromScript(the script of cd "Foo","FooBar") into tBar

function extractHandlerFromScript pScript,pHandlerName
   put lineOffset("on" && pHandlerName & space, pScript) into tHandlerBegin
   if tHandlerBegin is 0 then put lineOffset("on" && pHandlerName & 
cr, pScript) into tFooBar1
   if tHandlerBegin is 0 then put lineOffset("function" && 
pHandlerName & space, pScript) into tFooBar1
   if tHandlerBegin is 0 then put lineOffset("function" && 
pHandlerName & cr, pScript) into tFooBar1
   if tHandlerBegin is 0 then return empty
   put lineOffset("end" && pHandlerName & cr, pScript) into tHandlerEnd
   if tHandlerEnd is 0 then put lineOffset("end" && pHandlerName & 
space, pScript) into tHandlerEnd
   if tHandlerEnd is 0 then return empty
   return line tHandlerBegin to tHandlerEnd of pScript
end extractHandlerFromScript

If formatting is not so regular, you may need to account for multiple 
spaces between on/function/end and handler name.
