Ok, The right time to learn how to use the '--debug' option?
Code:
sort -k3nr --debug <<<"Server1 not found 1025 MAJOR some info here"

Code:
sort: text ordering performed using simple byte comparison
sort: key 1 is numeric and spans multiple fields
Server1 not found 1025 MAJOR some info here
            ^ no match for key
___________________________________________

mismatch!
Code:
sort -k4nr --debug <<<"Server1 not found 1025 MAJOR some info here"

Code:
sort: text ordering performed using simple byte comparison
sort: key 1 is numeric and spans multiple fields
Server1 not found 1025 MAJOR some info here
                  ____
___________________________________________

You see, a little dash appeared under the number?
This first key sorting rule worked. But there are more clues
Code:
sort -k4,4nr --debug <<<"Server1 not found 1025 MAJOR some info here"

Code:
sort: text ordering performed using simple byte comparison
Server1 not found 1025 MAJOR some info here
                  ____
___________________________________________

That's ok

Also
Try it like this
Code:
head -1 file
for i in CRITICAL MAJOR HIGH MEDIUM MINOR LOW; do
        grep "$i" file | sort -k4
done

Sorry, bad advice
