If the processing rules basically call for substituting a @context IRI with the content of the @context block at the referenced document, then requiring the processor to re-order the array so that referenced contexts are processed before in-line seems un-natural. In reality, I think this is an academic concern, and we can state that best practice is to process the contexts (remote or local) in the order listed.

CSS does not define an order except in most-specific to least specific, in-tag or in-document before loaded (AFAIR). JSON does specify an order.

In reality, I would expect that there would only be two entries, a remote and a local, but test cases could check for multiple remote and multiple local with order-dependent definitions.
