Pragmatic and more accurate than the path I was on. Thanks! I should have noted that this will avoid starting your scripts if run-parts is running, but it won't prevent run-parts from starting while your script runs. If that's important, then you'll have to modify both your cron jobs and the system crontabs that start run-parts, and use a lock of one sort or another.
