Follow the documentation for creating a part from scratch. The documentation “highly recommends” publishing the part using the default symbol . It is noted that the default symbol’s pins can be reordered setting the “Terminal Order” property for each terminal. However, despite setting the Terminal Order property from 1 to, for example, 16 for each of 16 Terminals, the pin ordering of the published component still uses alphabetical sorting. This issue was reproduced on Windows in Edge and Firefox. TL;DR: The “Terminal Order” property does not seem to work as the documentation says it should.
