Cannot control attribute ordering via rlm_perl

Hello List,

I am falling in the same trap as below quoted a few years back.
When using WiMAX, the reply attribute ordering is important.
Using rlm_perl which is used with "Splynx" ( messes up the order in the response and I can't seem to find a way around this.

Alan mentioned in a old post "suggestions welcome".
Wondering if there was a solution in the meantime or if anyone has a idea how to solve this (with perl)?

possible. My theory is that this is due to the hash-tables used as the
interface between the C and Perl worlds.

  Quite possibly.

  Yeah.  The server really needs to have a better way of handling nested
attributes.  Suggestions are welcome...

  Not using Perl.
