I think you have already solved your problem, but here is the handler
I use on OS X to determine whether an application is running:

function isAppRunning pAppName
  put "tell application " & quote & "System Events" & quote & cr into tScript
  put "return (exists application process " & quote & pAppname & quote
& ")" & cr after tScript
  put "end tell" after tScript
  do tScript as AppleScript
  return the result
end isAppRunning

(watch for line-wraps)
