Interesting method of doing it. I ended up using awk:
fn next_tag {
awk -v ctag'='`{wmiir read /tag/sel/ctl} '
NR==1 {ntag=$0}
$0==ctag {
ntag=getline?$0:ntag;
print ntag
}'
}
fn Key-$MODKEY^comma { wmiir xwrite /ctl view `{ read_tags | next_tag} }
fn Key-$MODKEY^period { wmiir xwrite /ctl view `{ read_tags | sort -r
| next_tag} }
