I've just published a new draft of SRFI 132 from John Cowan.

John said:

  This incorporates Will's comments on the ML.  Please also
  accept his pull request, after which I'll update the code.

  I have removed the "additional procedures" section,
  referring users to SRFI 32 instead.

I've incorporated Will's changes, too.  Will said:

  This pull request completes the reference implementation
  for SRFI 132, adds my proposed vector-select procedure,
  fixes two bugs, adds a far more comprehensive test
  program, and makes it easy to improve the performance of
  the primary sorting routines by using the R6RS (rnrs
  sorting) library if it is available.
