 - Do you get any error messages in any logs?
 - If you print [scratch discount_item]  and [scratch discount] above the 
[discount] tag, does it show the values you expect?
 - Have you tried to just use Perl instead of the [calc] block? 

[discount code="[scratch discount_item]"]
return $Scratch->{discount} * $q;
[/discount]
