Classify account when multiple classifications may be possible

I have a list of accounts for various services that are being implemented. Each service may have an implementation at a different stage, however, I want to classify the account based on the most favorable stage. I took the stages "launched", "on target", and "delayed" and translated them to 1, 2 and 3. Essentially if an account had a 1 and a 2, I'd want the account to be represented by 1. What function can I create to acheive this?
