I think I may be misunderstanding your question, but does the following
interaction not do what you want?

  $ racket
  Welcome to Racket v5.3.2.2.
  -> (define s "hello")
  -> (cond
          [(<= (string-length s) 5) 10]
          [(string=? s “hello”) 50]
          [(string=? (substring s 1 4) “ell”) 25]
          [else 130])
  10
