Dropping a suggestion (or distraction ;-) ). To get sortnumber added from regular value input. See /doc Convert#Time units: Module:convert can read all numberunitseconddisp=number inputs into seconds, and return the plain number-in-seconds only. That plain number to be fed to (=nested in)  to produce sortable code. All from a single article-editor number-space-unit input (restrictions might apply). Issue: number-unit separator is space in regular input, but Convert requires a pipe. Too fast or clear enough? -
