In BREVERB, double-click on one of the numerical value (e.g., "500 ms"). This lets you manually edit the value (e.g., "500"). The problem is that as soon as I hit a numerical key (e.g., "4"), the screenset changes to that screenset number.

So, the logic binding the numeric key ("4") to the screenset is too strong.

Does anyone else have this problem?

Two things - Click on the keyboard icon on Breverb to give the keystrokes to the FX;
 
If you use the number keys above the qwerty keys, they control screen sets, number pad keys do not.
 
Both go to Breverb if you click on the keystrokes icon.

I'm not in front of SONAR, but...   Does the same thing happen if you use the number pad (if you have one) instead of the number keys across the top?   I don't recall seeing this with th native PC modules, so I wonder if it's BREVERB in particular.    Or maybe TH2 as well....

This helped. Is there a way to enable the keyboard icon by default whenever a popup has focus?
