Description

The datatool user manual provides an example that uses a custom command called \switchargs to alter the sorting. This no longer produces the desire order.

Evaluation

This change in behaviour was caused by the bug fix strange behavior of \dtlcompare. It's now necessary to use \dtlcompareskipcstrue for this example to work. The user manual will be corrected in the next version.
