In this situation you don't need the decoder if you use inputs 1, 2 and 4 of the priority encoder.

MarkF:
You could use a small 8-pin microcontroller like a PIC12(L)F1822.
However, you would need to be aware of the input sample rate and propagation delay achievable.

Oh, well, there it is.  Problem solved.
