Duh?!?

3.6 Serial Data Output (DOUT)
The SPI serial data output pin is used to shift out the
results of the A/D conversion. Data will always change
on the falling edge of each clock as the conversion
takes place.

Change your clock idle from low to high, and see what happen.

That was easy

        high cs
        Pause 100 ' Pause to see display on LCD.
Main:
        LOW CS ' Enable ADC
        SHIFTOUT DataOut, Clock, 2, [%11000] ' Select CH0, Single-Ended
        high Clock
        SHIFTIN DataIn, Clock, 6, [result0\13] ' Read ADC
        HIGH CS ' Disable ADC
        Low Clock
        LCDOUT $FE,1,"ADC: ",dec result0
        PAUSE 100 'Pause long enough to read LCD.
        Goto Main

now read the datasheet to know why it works
