Cross-country uses rank point scoring. The final scores don't add up correctly. The 5 Orange runners come in 4th, 14th, 20th, 21st, and 30th. Add them together and the score is 99. Eastern scores were 1, 5, 25, 28, and 31, which add up to 90.
The correct scoring for the orange team is actually 89, not 99. They did indeed rank higher than the Eastern team.
