As posted by jhurshman on Macfixit, you can do this to edit your Info.plist inside the Help appilcation from Terminal:

sudo cp /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist.original; checkLine=`grep -n 'NSAppleScriptEnabled' /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist.original | awk -F : '{print $1}'`; theLine=`echo "$checkLine + 1" | bc`; sed -e "$theLine s/true/false/g" /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist.original > ~/Info.plist.nu; sudo cp ~/Info.plist.nu /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist

OR if you're paranoid and want to do it manually, you can walk through this recipe (again from Terminal):

sudo -s [enter password]
vi /System/Library/CoreServices/Help\ Viewer.app/Contents/Info.plist
type '/NSApple' to search for NSApplescriptEnabled
down-arrow to next line after NSApplescript, use 'x' key to delete the word 'true'
type 'i' key for insert mode, type 'false', hit 'esc' key
type 'ZZ' to quit and save
exit; exit

Your results should look something like this in the area you edited: 

<key>NSApplescriptEnabled</key>
<false/>

And basically, what you are doing is editing the NSApplescriptEnabled key in the Info.plist file inside the Help View application to be false instead of true.

Works for me!
