Why do you have quotes around $range, when none is present in the original? Do you want the replacement to have quotes?
If not, and you only want the number, try this:
Code:
sed -i "3s/.*/maxujobs ${range}/" /root/sge_scripts/night_sched_conf
If you do indeed want the double quotes around the number, try this:
Code:
sed -i "3s/.*/maxujobs \"${range}\"/" /root/sge_scripts/night_sched_conf
Note:
I always use brackets for safety.
The type of quote - single or double - does matter to the shell (usually bash or dash by default) when doing substitutions. Using bash/dash, a variable name in single quotes will not be expanded to its value, whereas in a double quote the variable will be expanded.

Reason: Spelling and such
