No. There's an old program called SCI Decoder that can export resources including audio and scripts, but there's nothing to help you read compiled scripts. It works for SCI0 and SCI1 games. It won't export from SCI1.1 games, however. There's another command line program called SCIDump, I believe, that can dump resources from SCI1.1 and SCI32 games. Again, no decompiling any scripts, though.
