Any reason they have to decay at all? It's not like orcs have a large lifespan (even the most deadly orc was 59%) and there is some fear of the orc hording overpowered things like phylacteries. Considering these are generally less popular adaptations anyways, why not? It'd also bring about more cross-orc loving.
