It's a valid hostname (numeric sub-domains are allowed in DNS), but it's not a valid FQDN. However I'm not convinced that newaliases should fail like this. Shouldn't it just create an empty alias database? Should Postfix be policing which TLD's are valid? It seems like that should be up to the receiving MTA.
