If you are scouting an area that is known to (or could) contain bear or cougar (pretty much statewide), and bear/cougar season is open, if you get the bear and cougar tags (only an extra $11) you can claim, very legitimately that you are hunting bear and/or cougar while deer scouting.
As noted, even if it's too early for bear or cougar seasons to be open, or you don't want to pay for the tags, as long you have the current year license you can state you are coyote hunting while deer scouting.
I think the only real issue is that you are not allowed to hunt coyotes at night with lights in areas open to general season deer or elk hunting during the respective seasons. Which isn't what you are wanting to do anyway.
