How to I delete a key/value pair from an OrderedDataStore?

Let's say that I create a standard value pair using SetAsync for an OrderedDataStore. How do I delete the pair without creating a new data store and moving the other pairs to the new one? (More specific for my problem, I'm creating a queue with the key as the time, and the value the user's playerID. When they leave the queue, I want their ID and time spent waiting deleted so other people aren't waiting behind someone that isn't in the queue anymore.)
