[ic] discount tag

Is there any way to use a variable with the [discount] tag?

For instance, I would like to discount an entire order by a dollar amount 
that is held by a scratch variable.  I have been trying something like:

[discount ENTIRE_ORDER] $s - [scratch VARNAME] [/discount]

I have looked at the docs and the only examples that I have seen use an 
integer instead of a variable.

I just want to know if this is possible or if I need to try it from another 
direction.

Thanks
