Optimization can be tricky

Put yourself in the computer's shoes, and also clarify what you need to 
accomplish. You are asking it to sort the entire list of 2000 records, 
but (if I understand) you only want a handful of those.

And it has already gone through all the records once before the sort. If 
you asked a human to do that, it would be a risky interaction. There 
might be raised voices when they present the neatly arranged file 
cabinet with files in a special order, and you deliver the punch line 
that you only need to pull a few. If you only need to pull 5 records, 
most people don't want to go through all 2000 files - twice.

So generally, don't use a sort after doing a complete loop on a big text 
list, use another method. Do unto your computer as you hope it will do 
unto you when they run the world. :)

(But I would be interested in the speed of your original code on LC 9 vs 
LC 6.7, just to see how engine optimization is faring. I'm surprised it 
took a minute.)

Best wishes,
