Ignore the numbers. Look at the results on a calibrated monitor and on a Vectorscope & Parade Waveform Monitor.
If you want accurate Color Temperature adjustment, use the OFX Chromatic Adaptation plug-in and switch it to Color Temperature mode, then use the slider to get a reasonable overall balance. This will work, at least in cases where you don't have access to the Raw controls. In extreme situations (like very warm/yellow 3200° material shot with the camera stuck in 6500°), you might have to add a couple curve nodes to pull some yellow and/or balance the picture with Primaries. Temp & Tint alone are not enough.
