Thing were sort of OK as is from the previous definition, but was missing:
config vlan 1800 tagged trk1 forbid trk2,trk3 ip ospf area 4 ip ospf passive wr mem exit exit
The configuration was missing completely, so:
config router vrrp vlan 1800 name cscore ip address 172.19.0.2/24 ip helper-address 129.97.15.253 tagged trk1 forbid trk3 ip ospf area 4 ip ospf passive vrrp vrid 2 backup virtual-ip-address 172.19.0.1/24 enable exit exit wr mem exit
