"Ignore" seems to be the right thing. The motivation is to be able to write software (such as a DNS stub resolver) where using the CoA as source is better for performance when the node is indeed a mobile IP node away from home. But when this is not the case you don't want to see a failure or require that the application only set PREFER_SRC_COA when it knows it is running on a mobile node away from home. Makes sense to make that clear in the spec.
