Not sure if this is the correct syntax, but I guess this shows what's going on:

: stain at ralph ~;echo '(currency "MXN" "GBP")' | gnc-fq-helper
(("MXN" (symbol . "MXN") (last . 0.05321) (currency . "GBP")))

: stain at ralph ~;echo '(currency "NOK" "GBP")' | gnc-fq-helper
(("NOK" (symbol . "NOK") (last . 11.006) (currency . "GBP")))

: stain at ralph ~;echo '(currency "GBP" "NOK")' | gnc-fq-helper
(("GBP" (symbol . "GBP") (last . 9.0861) (currency . "NOK")))


And using Finance::Quote directly fails with NOK:

#!/usr/bin/perl
use Finance::Quote;
$q = Finance::Quote->new;
$conversion_rate = $q->currency("NOK", "GBP");
print $conversion_rate . "\n";

# 11.008 instead of 0.11008

Also see http://sourceforge.net/mailarchive/forum.php?thread_name=4BA7F6BB.30909@bjdean.id.au&forum_name=finance-quote-devel
- so this should be discussed with the Finance::Quote developers.

I contacted Yahoo about this (which seems to be the faulty source
behind Finance::Quote):
