Time Duration Returned in Number Format

This solution to convert seconds into a time duration works correctly, however, the returned text sorts only by the first number in the string and not by the durations' actual magnitude.

The screen capture below is an example, where 3,161:29:60 would be preferred to sort at the top of the list as being the longest duration and so on -

The only way I can get the desired result is by sorting the seconds, but having the seconds as a column in the table is not a desired result as shown in the screen capture below -

Is there a good way to have duration sorting from greatest to least aside from using the seconds for sorting?  I don't see there's a way to hide a column either..  Thanks in advance.
