Check for mounted DFS share with exists in apple script

Question

OS: OSX Mountain lion.
Can any one advise how to detect if a DFS share is mounted or not?
I have been using the following code:
set volumeLabel to "R$"
tell application "Finder"
  exists disk volumeLabel
end tell
Which works fine with a normal SMB shares or attached hard drives but I cant get it to work with a DFS Share, it always returns false (see attached screen shot.
Also tried:
if volumeLabel is in (do shell script "/bin/ls Volumes") then
          return true
else
          return false
end if
Which didnt work with a DFS Share aswell.
Any help appreciated.
Cheers,
Richard

Hi,
Since you're checking to see if a value exists in the Desktop key, you can do something along these lines:
If (Get-ItemProperty -Path 'HKCU:\Control Panel\Desktop' -Name SCRNSAVE.EXE -ErrorAction SilentlyContinue) {
Write-Output 'Value exists'
} Else {
Write-Output 'Value DOES NOT exist'
EDIT: Sam, what version of PowerShell are you running? Your code doesn't seem to work for me on v4:
PS C:\> Push-Location
Set-Location "HKCU:\Control Panel"
$Result = Test-Path -Path ".\desktop\SCRNSAVE.EXE"
Pop-Location
$Result
False
