[nsp] BGP community issue or provider issue?

I'm having trouble making use of BGP communities with one of my transit
providers.  i.e. I'm setting a community string via a simple route-map,
but they seem to either not receive it or ignore it.

Here's part of the config:

router bgp 6364
 neighbor a.b.c.d remote-as 1239
 neighbor a.b.c.d update-source Serial1/0
 neighbor a.b.c.d version 4
 neighbor a.b.c.d send-community
 neighbor a.b.c.d soft-reconfiguration inbound
 neighbor a.b.c.d distribute-list 190 in
 neighbor a.b.c.d route-map SPRINT-NO-METRIC in
 neighbor a.b.c.d route-map sprint_prepend out
 neighbor a.b.c.d maximum-prefix 150000 90
 neighbor a.b.c.d filter-list 1 out

route-map sprint_prepend permit 10
 set community 65003:6447

>From their NOC, I'm getting the run-around.  First they tried several
times to tell me what I was doing made no sense (though it's copied from
docs on their web site, which I referenced in my emails to them).  Now
they're saying they understand what I'm trying to do, but they're not
receiving any community string because I have no match statement in the
route-map.  I know I don't need one.

I know I don't need one because on another router, with another provider, 
I have:

router bgp 6364
 neighbor e.f.g.h remote-as 701
 neighbor e.f.g.h send-community
 neighbor e.f.g.h version 4
 neighbor e.f.g.h soft-reconfiguration inbound
 neighbor e.f.g.h distribute-list 190 in
 neighbor e.f.g.h route-map UUNET_INPUT in
 neighbor e.f.g.h route-map tell_uu_to_prepend_one out
 neighbor e.f.g.h maximum-prefix 150000 90
 neighbor e.f.g.h filter-list 1 out

route-map tell_uu_to_prepend_one permit 10
 set community 701:1

And funny thing...this one works as it's supposed to.

The working config is a 7513 running IOS in the 12.0S train.
The non-working config is a 7206 running IOS in the 12.1T train.

Is there any chance this is a config issue or IOS issue on my end, or do I 
need to keep banging on this provider's escalate button until I get 
someone who knows what's going on?
