Your script works okay here, meili. But the Transcript Dictionary says this:

"The word break appears on a line by itself, within a case section of 
a switch control structure."

And this:

"The break command should not be used outside a switch structure. If 
it appears outside a switch structure, it has the same effect as the 
exit control structure."

So it's probably better form to use something like this:

repeat until the mouseClick
   do stuff
end repeat

Or this:

repeat
   if the mouseClick then exit repeat
end repeat
