I think that unless you can check the std err in the shell call, you won't be able to detect "bad passwords", so this may be failing silently at the shell call. I'm not sure of this and would welcome correction from anyone with better info.

tell application "Keychain Scripting"

set myKey to "name of your admin account in keychain"

tell keychain 1

set chosenKey to the first key whose name is myKey as string

set adminpwd to the password of chosenKey as string

end tell

set myScript to "do shell script {\"echo\" & quoted form of " & adminpwd & " | sudo periodic daily ;echo 'Periodic tasks performed'\"}"

display dialog "The daily, maintenance scripts have completed."
