It seem worth pointing out that this is why many of us like ISO8601 
dates, which are written from largest component to smallest component.  
For example:

    2020-05-04

They have the convenient property of sorting lexically as they would 
sort numerically.

But David's right on in saying that if you're comparing numbers, do it 
numerically. Comparing text when the underlying thing isn't text is the 
wrong approach.
