Cannot confirm this.

[flag type=write table=country]
[flag type=write table=state]

Reset values, cart: [calc] %$Values = (); @$Items = (); 1[/calc] <br>
Reset discount ENTIRE_ORDER. [discount ENTIRE_ORDER][/discount]
Set SalesTax to 
    [calc] $Config->{SalesTax} = 'junk' [/calc].
<p>

order [cgi name=mv_order_item set=os28004]
quantity [cgi name=mv_order_quantity set=10].
[cgi name=mv_todo set=refresh] and update. [update process]
<p>
Cart contains: [calc] uneval($Items) [/calc]<br>
subtotal=[subtotal] salestax=[salestax]
<p>
    [tmp oh_key][data table=state column=code key=OH foreign=state][/tmp]
    Set OH salestax rate to
        [data table=state column=tax key="[scratch oh_key]" value="10%"].<br>
    Set SalesTax to [calc] $Config->{SalesTax} = 'multi' [/calc].<br>
    Set US Tax mode to
        [data table=country column=tax key="US" value="state"].<br>
    Country to [value name=country set=US],
    State to [value name=state  set=OH].<br>
    subtotal=[subtotal] salestax=[salestax]
<p>
    Set OH salestax rate to
        [data table=state column=tax key="[scratch oh_key]" value="5%"].<br>
    subtotal=[subtotal] salestax=[salestax]
<p>
    Discount ENTIRE_ORDER. [discount ENTIRE_ORDER] $s - 10 [/discount]
    subtotal=[subtotal] salestax=[salestax]
<p>
    Reset discount ENTIRE_ORDER. [discount ENTIRE_ORDER][/discount]
    subtotal=[subtotal] salestax=[salestax]
<p>
    Discount item os28004. [discount os28004] $s * .9 [/discount]
    subtotal=[subtotal] salestax=[salestax]
<p>
Set SalesTax to 
    [calc] $Config->{SalesTax} = 'junk' [/calc].
    subtotal=[subtotal] salestax=[salestax]

The above behaves properly on both 4.8 and 4.9.
