Unfortunately, this is one of those things that you have to learn by playing and "feeling" rather than "knowing". Some pointers, though.
Try playing a style (cascara, rumba, etc.) with clave 3-2, and then try clave 2-3. Also try Cuban clave 3-2 and 2-3. See which one seems to fit and groove best. Usually, that's the right one.
Another way I tend to figure out claves is to see the interplay between the bass "swing" grooves and the clave. In salsa tunes (or jibaro-tipico tunes, or bomba, etc.) play bass styles that are "swingy", "anticipated", or "not on the beat" (such as in Plena or Merengue). It depends on the bass player too, but, think Bobby Valentin: nice, long, legatto, swing bass grooves. Now, if you are playing these ancipated, legatto beats on the bass, the question you should ask yourself is: are the bass beats landing on with the clave that you are playing.
Try it. Start playing a 3-2 clave, counting on 4/4. Play along with a bassist (or listen to the bassist, if it is a recording). If the clave you are playing seems to be landing too straight with the bass player's swing grooves, you may be playing the clave backward. Try 2-3 instead. If that one seems to "interlock" in the spaces "between" the bass's swing grooves, that is most likely the clave that is correct.
Sometimes, claves are hard to discern, because both may sound good. In those cases, listening to the interplay between bass, piano, congas, timbales, etc. may help you locate the clave. Listen to where the cascara patterns on Timbale are playing. listen to the Conguero's placement of open tones and slap/muted tones. Listen to the emphasis of the piano player (is he emphasizing the first part of the measure, or the second). And, of course, listen to the bassist's grooves.
That's the best advice I can offer. Remember....the clave should flow, interlock, weave back and forth, and groove with the song, NOT LAND WITH THE BEAT. The best way to see this is to watch a Cuban rumba, the way the dancers weave to the conguero's alternation between open tones and muted tones. The way the clave "flows and interlocks" with the percussion pattern, rather than fit on the beat, like in rock, funk, plena, or merengue styles. Finally, listen to a LOT of Latin Music. Your body will sort of "get adjusted" to the music's structure, and you will begin to "feel" the clave.
Hope that helps!
