Strange - are you sure it is picking up the right version of the lens ?
I just added the following tests to your module, and they pass:

        test lns get "MOUNTD_PORT=892\n" = { "MOUNTD_PORT" = "892" }
        
        test lns get "# MOUNTD_PORT=892\n" =
          { "MOUNTD_PORT" = "892"
              { "commented" } }
        
        test lns put "MOUNTD_PORT=892\n" after clear "/MOUNTD_PORT/commented" =
          "# MOUNTD_PORT=892\n"
        
        test lns put "# MOUNTD_PORT=892\n" after rm "/MOUNTD_PORT/commented" =
          "MOUNTD_PORT=892\n"

Also, playing around with augtool seems to confirm that the lens does
what it's supposed to do. Be careful: you also need to change
shellvars.aug and make sure it doesn't match /etc/sysconfig/nfs - that
actually might be your problem.

Does 'print /augeas//error' in augtool produce any output ?

Yes, that will cause both comment and int_entry to match a commented
setting. BTW, I recently added [1] to the Wiki to explain better what
all those typecheck errors mean.
