Don't we say the same thing ? Quoting this doc.:
 
 " The node attribute TLV must appear in exactly one TE LSA originated
   by a router. Further only one node attribute TLV must be advertised
   in such a LSA. A node attribute TLV must carry at most one Node IPv4
   Local Address sub-TLV and at most one Node IPv6 Local Address sub-
   TLV."
 
Hence, to your question:

> Should a Local TE Router-ID sub-TLV be encoded 
> *before* each Node IPv4/IPv6 Local Prefix Sub-TLV? 

it is a one to one correspondance in each of these LSAs.
-d.
