[gridengine users] PE batch job scheduled in interactive queue

This feels like I ought to know better, but..... I currently have two queues: "batch.q" which is configured to accept both batch and interactive jobs, and "interactive.q" which just accepts interactive jobs. Both are configured to use a PE 'smp' which is configured as $pe_slots. The queues are configured such that batch.q is Sequence Nr 0, and interactive.q is Sequence Nr 1. This means that when the cluster is busy, nodes will be oversubscribed by (niced) interactive jobs (characterised by short, sharp bursts of activity, with long idle periods) only, thus preserving some sense of "availability".
Our cluster was busy the other day, and to my surprise I found that when I submitted a parallel job using "qsub -pe smp 4 myScript.com", it ended up scheduled in interactive.q. Huh? interactive.q is not configured to accept batch jobs. Anyone know what might be going on?
