That returns 1 record (and same if I correct @rownum to @row_num)

queue_name jobs_pend jobs_run
others           471      457

If I run the sub-select without the CASE like this

SELECT
   @row_num, queue_name, jobs_pend, jobs_run
FROM
  (
  SELECT
    @row_num := @row_num + 1,
    queue_name, jobs_pend, jobs_run
  FROM
    queues, (SELECT @row_num := 0) r
  ) q

it returns

@row_num  queue_name  jobs_pend jobs_run
