You have two choices:

1) Evaluate the "varname" scratch when the discount is defined:

[discount code="ENTIRE_ORDER" interpolate=1]$s - [scratch varname][/discount]

2) Evaluate the "varname" scratch when the discount value is calculated:

[discount ENTIRE_ORDER]$s - $Scratch->{varname}[/discount]
