Please keep in mind that regardless of the ordering r will be in the middle of the ordering.
The quickest way to answer this question especially if you were running out of time during the actual GMAT test is to use an integer property which would state that if r, s and t were positive integers with each greater than 1, then the ordering would have been t < r < s.
But since r, s, t < 1, then the ordering would be the other way around => s < r < t.
Answer D : s < r < t
