I think you would need to do something like this:

my $si = $d->get(873, 10415); # Get 3GPP-Service-Information
my $sub_id = $si->get(443, 0); # This is IANA attr, vendor is 0
my $subscription = $sub_id->get(444, 0); # The Subscription-Id-Data

I used attribute numbers and vendor numbers for brevity. I do not think
there even is a Subcription-Id-Data in $p, the RADIUS converted request?

However, I did not check it myself but not all Diameter attributes can
be converted. The above should work in any case, because it fetches the
value from the Diameter message.

Thanks,
Heikk
