Check the documentation:

the level property:

"Worker Priority. Valid values are 0-3. The functioning workers with the
lowest level will be checked for the lowest lb_value, and if found will
be run. The upper level workers are only checked upon failure of all
workers on ALL of the levels below them. This is very useful for
implementing failover withing a cluster. "

Beware of bugs in the above code; I have only proved it correct, not
tried it.
