dig +multiline will show you the key tag, or you can use dnssec-dsfromkey
and pull the tag out of the result, e.g.

$ dig dnskey $zone | dnssec-dsfromkey -f - $zone | awk 'NR == 1 { print $4 }'

Humber, Thames: Variable 3 or 4, becoming northeast 4 or 5 in Thames. Smooth
or slight, occasionally moderate later in Thames. Occasional rain at first.
Good, occasionally poor.
