I think you should judge SICP on what the authors' own intentions were, not on things they weren't trying to do. I didn't get the feeling that cleanness was emphasized or encouraged (any more than in any class). There are other classes that cover fundamental algorithms like sorting, SICP isn't about that.

You might find the authors own critique of SICP interesting:

So what WERE they trying to do?

BTW, here is a list of people who had criticized SICP. The list is full of heavy-weights:

    Philip Wadler
    Donald Knuth
    Eric Raymond
    Richard Bird
    Paul Graham
    Guy Steele
    Robert Harper
    Matthias Felleisen
    Daniel Friedman
    Christopher Strachey
    Peter Landin
    John Backus
