COR would be what I would use for this. If you share your full running configuration and outline in detail what you’d want to achieve we can see if we can help you out with the needed configuration for this.
In that case, I would suggest using a prefix to differentiate the calls and ensure they land on the desired dial-peer matching the calls.
This is specifically for users who use three lines on the same phones.Since the SIP COR will be on the pool and not the DN like the SCCP.

These articles should summarize quite well what you'd need to do.
Configuration Cisco CME COR List
Configuring Class of Restrictions (COR)
Do note that if you're using SIP devices in CME those are configured with other configuration elements than ephone, so that part needs to be adopted to fit your needs.
Basically what you'd need is a corlist that is used in the inbound direction on the ephone dn and/or voice register pool and then another, or the same could also work depending on your needs, that is used in the outbound direction on the dial peer that uses the specific translation for that PSTN phone number.
Something like this could work as an example for one of the numbers you outlined.

You mentioned in your post that you have tried a solution based on the Corlist. However, there is no configuration required for the core on the shared configuration for that to work.
I echo @Roger Kallberg : COR will be the solution for you.
Well you never said anything about that you’d be using all 3 numbers on the same device. That’s an entirely different thing.
In that case, I would suggest using a prefix to differentiate the calls and ensure they land on the desired dial-peer matching the calls.
This is specifically for users who use three lines on the same phones.Since the SIP COR will be on the pool and not the DN like the SCCP.
Just be aware of if you do not have COR on the dial peers that you intend to be used by the phone that has all 3 DNs there is nothing stopping the other phones to use these dial peers as well. See this table from this document, Configuring Class of Restrictions (COR), for more details.
You might want to have a look at this great document on what is possible for call routing in IOS. Explain Cisco IOS and IOS XE Call Routing Although do note that since your using CME there are limitations as the inbound dial-peer for the devices would be the one that the system creates for you based on the CME configuration. So I'm afraid not all options are on the table. Hopefully there are some nuggets in it, if not for this I'm sure you'll return to it many times as it's one of the most useful documents in my view.
