or
if ( (%cpu <= 60) && $isprocess(coolmon.exe) && !$isprocess(wscript.exe) ) {
Since if the %cpu value is 61 or greater you wont do it you should check that first, then it never needs to check the $isprocess's if %cpu is 61 or up.
Then depending on which you think is more likely to be false place that as the first $isprocess
if wscript.exe is almost always running use first option
If coolmon.exe is almost never running use second option
Either well reduce the $isprocess load during the top 40% of CPU usage.
