Description
### Describe the enhancement requested
See discussion in #34437. My workaround of reversing the sort, taking head, and re-reversing is inefficient and is not possible when the data has implicit order.
### Component(s)

Contributor guide
Research direction
Start by reading the discussion in #34437 and locating the C++ FetchNode implementation. Compare the requested tail behavior with the existing head behavior, especially for data with implicit order; done means tail works without reversing the sort and re-reversing the result.
