You completed the mission under 10 minutes, which is the maximum time allowed for maximum time bonus score of 25,550. Once you pass the 10-minute mark, the time bonus will start to drop rapidly.

Having a destruction score of 11,350 will give you a combined score of 36,900. From what I gather, 36,000 is the minimum combined score needed for S rank. I am still collecting more scores for various missions, so I won't update the S rank requirement here until I get enough to be sure of it.
