Unfortunately, the db is not aware of what the gui wants in terms of sort and so on. The system:limit predicate (which is how the 10k limit works) chooses a random sample of the larger search.
If you add something like 'system:size<100KB' to your query, the sampled result will be more accurate. If you set the 100KB lower, the result set will have less than 10k results, and you will get what you want.
