Should they? Or is there a possibility that it may oscillate around 10e-3? And if not does this indicate a problem somewhere?

Oscillations/fluctuations are not indicative of convergence. It is the residual value about which they fluctuate that matters.

Would you say that it points to a mesh size problem in the first instance? It's cavity flow with an inlet and outlet.
