There might not be a good answer to this. The datomic result set, is it ordered in any way?
queries that don't use aggregation (i.e. those whose result would be a set) will have a stable order for the same input
but queries that use aggregation I'm not sure you can rely on repeatable order because they may perform some parts of the aggregation in parallel, and the result is an ArrayList
So basically, no, there is no order you can really depend on. datalog operates in a set-wise fashion
If the result set is the same (same values in it, all hashing the same) and the collection implementation is the same (uses same hashing algorithm, etc) then it's likely the same
