FR 3.0.1 + CUI + MS-MPPE-*-Key issues

As part of the Moonshot project, I've upgraded my FR to 3.0.1 (plus the MySQL schema and the SQLite API fixes, because both are required here). I've now discovered an issue (I don't know if this is similar to what Stefan Winter raised recently about "Re: 3.0.x: Session resumption and CUI calculation" or not), where I have two scenarios and two items in Access-Accept that need to be there, CUI and the MS-MPPE-*-Key attributes:

1. FR 3.0.1 with use_tunneled_reply = yes, left as-is.

- auth with pam_gss: CUI present, multiple sets of MS-MPPE-*-Key present. (boo! GSS doesn't like multiple sets!)
- auth with rad_eap_test: CUI present, one set of MS-MPPE-*-Key present. (hooray! I have a CUI!)

2. FR 3.0.1 with use_tunneled_reply = no, modified to update outer.reply

- auth with pam_gss: CUI present, one set of MS-MPPE-*-Key present. (hooray! GSS now works!)
- auth with rad_eap_test: NO CUI present, one set of MS-MPPE-*-Key present. (boo! No CUI = problem!)

So, my question is, is this intended or unintended behaviour, and if it is unintended, is there anything we can do (with unlang or the like)?

I've compressed the four sets of authentications and parked them here (apologies for that, but I believe the mailing list has an attachment limit):
