Custom sort order with numbers

Hello everyone!
I’m trying to sort my data with a custom sort order but it doesn’t work.
Here’s my case:
I have for example one column with a bunch of numbers and i want to sort them not by ascending or descending order but by a custom order made by me. This custom order would be something like: 72,1,4,9,111,320,etc

I tried to do a custom sort order and then try to sort my column with this, but it didn’t work. Any ideas on how i can do this?

Thank you very much!
