Just a note… my temporary workaround is to make the “Display” value for Status be " Status" (note the space) and not simply “Status” and therefore it comes first.
Most examples refer to a simple table like this [“Status”,“Description”,“Owners”, etc…]

This is definitely a bug. The tab list control is still in preview. I would try another authoring version of Power Apps which can be changed via Settings > Support > Authoring Version.
Will it work if you don’t use the SortByColumns function and simply use nfColStatusTabs in the Items property of the gallery? Sorting does not appear to be necessary since its already in the correct order.
