I've done exactly what your thinking, and they should be fine. Long as you get them in well before ground freezes. If they come in a cardboard type container, just split the sides of the container in about 3 spots. In your hole mix up a bag soil mixture for fruit trees, plant, heel it good to remove any air pockets. Then be sure to place a good wood chip base around them. Also as a word of advice I like to use certain types of apple trees, that hold apples to later in fall, becasue thats when archery season starts. Do me no good to plant apple varieties that drop their fruit in August. Just something to think about. You'll also want to fence them in, the deer will eat them up good on you if you don't, and your just wasting $$. I've also had bucks rub the trunks, and kill a few on me. The fencing prevents it.
