If it is already inside controlled airspace, it is of equal priority to all other traffic in there, unless there is traffic with a higher flight priority category. If it's outside wanting to join, it's prioritised just like VFR traffic is. The only difference in that scenario being that it may be easier to separate IFR traffic from everything else hence a lower overall workload compared to VFR traffic or vice-versa.
I must mention that I don't control any Class D control zones though and it has been a while since I did.
