You are using the equivalent value to sort[2] as sort parameter in toc macro. If you don’t have the field 2 in the tiddlers you can’t ordered them.

See how sort works as parameter in toc macro and how it works as filter operator.

Thus sort[TOCOrder] means “sort by the values contained in the TOCOrder field”
