Currently the ARM will return an error status when a reply from a shard does not contain a $sortKey. This results in a DocumentSourceMergeCursors triggering a uassert here.
A shard returning a document without a $sortKey when the merging node was expecting one represents a bug in the query planner/engine. Raising this error condition as a tassert will allow our AF infrastructure to capture this failure and find bugs like SERVER-103724.
