At the moment you can only have one private algorithm per key type world wide. 

This is all to do with how you prove a zone is to be treated as insecure.   If example.com is using private.example.com and example.net is using private.example.net how done  validator that knows about private.example.com prove that example.net response are to be treated as insecure when there is a DS with PRIVATEDNS returned?

Two questions I didn't see addressed:

Why would a zone need to be signed with multiple private algorithms?

Why isn't it sufficient to treat all private algorithms as a single algorithm for DS purposes, and distinguish by the Key Tag and/or trial hashing?

Abstract:

  When DS records where defined the ability to fully identify the
  DNSSEC algorithms using PRIVATEDNS and PRIVATEOID was overlooked.

  This documents specifies 2 DS Algorithm Types which allow the DNSSEC
  algorithm sub type to be encoded in the DS record.
