applescript assign mouse click to random keystroke

I am trying to make a script that enables a mouse click to run through a string of keystroke values, moving down the keystrokes one at a time with each successive click. I am not having much luck.

Even better would be if the separate keystrokes can be triggered randomly and not sequentially with a mouse click. Any help would be great. Thanks

repeat 10 times
delay 1
tell application "System Events"
    tell application process "TextEdit"
        click (click at {10, 10})

        keystroke "6"
        keystroke "6"
        keystroke "0"
        -- ...
        keystroke "6"
        keystroke "4"
        delay 1

    end tell

end tell

end repeat
