But, I would like to get just one of the handlers from a script via

Most of the solutions presented so far make assumptions. For example,
there can be more than one space between "on" and the handler name.
In Navigator I use this to retrieve a list of the handler names:
repeat for each line L in tText -- tText is the script
if word 1 of L is among the items of "on,function,getprop,setprop"
then
put L & cr after tMenuText
end if
end repeat
So to get the handler you would be doing something like:
put 0 into tLineNumber
put false into tEnteredHandler
repeat for each line L in tText -- tText is the script
add 1 to tLineNumber
if word 1 of L is among the items of "on,function,getprop,setprop"
and \
word 2 of L is tHandlerName then
put tLineNumber into tStartLineNumber
put true into tEnteredHandler
end if
if tEnteredHandler and \
word 1 of L is "end" and \
word 2 of L is tHandlerName then
put tLineNumber into tEndLineNumber
exit repeat
end if
end repeat
-- if tEnteredHandler is false, we didn't find the handler
-- if tEnteredHandler is true, tStartLineNumber is where it starts,
-- tEndLineNumber is where it ends
