As far as I know, the song has nothing to do with Kubrick?s movie, but with a stage production for A Clockwork Orange performed by the Royal Shakespeare Company, in 1990. It seems that Bono and Edge created other songs for the play, but only Alex Descends into Hell was released on CD.
There is this quote from Edge on the song, it?s from Propaganda: "I wouldn?t expect a U2 fan to recognise this music as that of Edge and Bono, except perhaps on a couple of tracks. It is not really to do with U2. It?s a different attitude."
Btw, The Clockwork Orange the movie is great. Shocking, but still a great movie.
