Ive been asked a question about sorting on an enterprise keyword column and it doesnt seem this is possible. Ive also looked to create a view and as expected its not available in the sorting dropdown. Are there any workarounds for this?
According to Create a Managed Metadata column
In the Multiple Value field section, specify whether you want to allow multiple values in the column. If you allow multiple values, users will not be able to sort on this column in list views
Enterprise Keywords column (
TaxKeyword) is Multiple Value field it could not be specified in List View sorting.
