The priority algorithm is a numeric priority queue. Normally, the priorities are established such that lower values are considered to have higher priority. For example, a job with priority 1 will have a higher priority than a job with priority 10.
The default priority of all jobs is set in the Supervisor configuration, like so:
supervisor_default_priority = 9999
If this configuration parameter is not set, jobs submitted will have a default priority of 9999. Job priority can also be set by the user on job submission, subject to possible limits set by supervisor_highest_user_priority
