See yesterday's message on interpolation order; nothing happens with 
[scratch listing_counter] in your code until all [loop]'ing is done. Try 
something like this instead:

[set listing_counter][/set]
[loop list="1 2 3 4 5 6 7 8 9"]
[loop-last][calc]return 1 if ++$Scratch->{listing_counter} > 1; return 
0;[/calc][/loop-last]
[loop-code] - [scratch listing_counter]
[/loop]
