Yuma 5:7

All the work that was done by the cohein gadol while wearing his white clothes had to be done in order. If he sprinkled the he-goat before the ox, he had to repeat the sprinkling of the he-goat after the ox.

If the blood spilled out of the cup before he completed a full set of sprinkling which included sprinkling in the holy of holies, sprinkling on the paroches, and sprinkling on the mizbaiach, he must start over from the beginning of that set.
