Users have been able to configure rules for sorting by categorical variables in Architect, but they were being sorted as strings. This PR fixes sorting functionality for categorical variables to actually sort by the values provided.
The hierarchy for sorting is determined by the order that the values are defined in the variable definition. This user-supplied hierarchy is assumed to be high to low, to maintain consistency with the hierarchy sort used currently for sorting by ordinal variables.
In cases of items having multiple values in a category array, presence of a category is ranked higher than absence of. For instance [“A”, “B”] is considered higher in the hierarchy than [“A”].
