I need to sort all records by the last 4 digits in a particular column.
ie, my data looks like

alskjflkja0023
lkahsflkjf0021
mnslfkjas0019

I need to order all records by the last 4 digits. Any ideas on
how to go about doing that? All entries are 17 characters
long so it would be the right most 4 digits of the 17 character
string. Thanks!
