Thanks, Chipp... my version uses the pendingMessages to cancel the "doClick"
command if the user actually double-clicks:

on mouseUp
  send "doClick" to me in (the doubleClickInterval) milliseconds
end mouseUp

on mouseDoubleUp
  put lineOffset(",doClick,",the pendingMessages) into tLine
  if tLine <> 0 then cancel item 1 of line tLine of the pendingMessages
  --> doDoubleClickStuff
end mouseDoubleUp

on doClick
  --> doSingleClickStuff
end doClick

It's a bit shorter, but depends on the pendingMessages, so if you think some
external force may muck with the pendingMessages during the
doubleClickInterval you may wish to go another route. But it's worked for me
for years...
