Another peasibility:

>perl -wMstrict -le "my $s = '86f,934e,92,102i,14,19,222,'; ;; my ($a,$b,$c,$d,$e,$f,$g) = split m{ [[:alpha:]]* , }xms, $s; my $sum = ($a+$b+$c+$d+$e+$f+$g); ;; print $sum; " 1469

Update: Or even:

>perl -wMstrict -le "use List::Util qw(sum); ;; my $s = '86f,934e,92,102i,14,19,222,'; ;; my $sum = sum split m{ [[:alpha:]]* , }xms, $s; ;; print $sum; " 1469

Also (tested):  my $sum = sum $s =~ m{ \d+ }xmsg;

    [Corion]: Meh. Once again I find that SQLite doesn't support window functions and I want to use those nowadays :-)
    [erix]: Look what I found! :P
    [Corion]: Hmm - actually, I don't need them, even though they'd be nice. I just want the (say) 10 latest images, and that's easily done with a limit 10 offset 0 clause, as I don't need all top 10 images for all users.
    [Corion]: erix: Sure, but this is for a really-lightweight application and I'm replacing a CSV file / JSON file for user configuration with SQLite (and optionally, Pg) :)
    [erix]: isn't a texty format handier for configs?
    [Corion]: So far, I've avoided having even a user database by storing the user information in a (signed) cookie that the browser keeps for me, but as I want to be able to lock users, I need a second storage option :)
    [Corion]: erix: It's needed for keeping the list of users and the list of tags associated with an image, and for keeping the images with users. I want an easy way to know if an image can be deleted, which means that it can't be referenced by any tag anymore. ...
    [Corion]: SQL feels like a natural choice here :)
