Hi,
sad thing but scoreboard queries doesn't support math. There is special type of filed called DERIVED field which have possibility to concatenate strings but I'm not sure about operations with digits. To make it possible, you could vote up for idea to extend DERIVED attributes: Extend DERIVED attribute
Regarding to your scenario, as a workaround without publish new attribute, you can define query in this way:
(active = 1) AND ( (int2 >= 2) OR (int1 >= 1 AND int2 >= 1) OR (int1 >= 2) )
other way is to publish new attribute which will store sum of these fields and will recalculate it on change.
