L2W Script - How to buy item 8596

Hello.
I have Oracle L2Walker 2.09b, L2 Hellbound.
Can sbdy tell me how to buy

Code:

Scroll: Recovery (Grade C)[ID=8596]

I need to buy it in my script. Command

Code:

BUYITEM(Scroll: Recovery (Grade C)[ID=8596],10;)

doesn't work. Any other item, like healing potion working.
For example, command

Code:

BUYITEM(Lesser Healing Potion[ID=1060],10;Scroll: Recovery (Grade C)[ID=8596],10;)

is buying only 10 Lesser Healing Potion, Scroll: Recovery (Grade C) no.
Command

Code:

BUYITEM(Scroll: Recovery (Grade C)[ID=8596],10;Lesser Healing Potion[ID=1060],10;)

is buying nothing.
Looks like item 8596 cancel command, which is executed.
Is there any other way to buy this item by script?
Thx for any help.
