Poppy's answer will turn off ALL your scripts, not just that one so i suggest that you do this:
1) Put "#name off" at the beginning of the script
2) Put "#name end" at the end of the script
3) Enable it via /enable #name
4) Disable it via /disable #name
Note: if you want the script to be on by default, replace the '#name off' by '#name on'.
Hope it helps.
