SRV subdomains

[PrinceLuna]

I run 3 Team Fortress servers on the same IP (with ports 27015, 27016, and 27025), and I am trying to get subdomains so players can enter the domain instead of the IP to connect, I have it kinda working, but not quite.

I have three separate "A" records (Server1, Server2, and Server3) that redirect the webserver domain to 216.52.143.121. Now I have the SRV records,
_hl2._udp.server1 to server1.clublunaservers.com:27015
_hl2._udp.server2 to server2.clublunaservers.com:27016
_hl2._udp.server3 to server3.clublunaservers.com:27025

Now after waiting ample time for the "A" records to register, I test if this works, and all three subdomains connect the client to Server1. Is there something I did wrong? Or is multiple SRV subdomains unsupported by Valve game servers?

SRV records are only supported by a few applications, and unfortunately Steam games (including TF2) are not among them.

For our customers, SRV records only come up in reference to TS3 and Minecraft.
