Those berries are unobtainable in-game; that must be why they aren't used in any metagame.
Their effects are actually in our Item Descriptions thread in the D/P Analyses--except for the Micle Berry.
Since Custap has been explained, I'll go into the others:
Micle Berry - "pinch" berry that raises Accuracy one stage
Jaboca Berry - if holder is hit by a Physical attack, the foe takes damage equal to 1/8 of its max. HP
Rowap Berry - Jaboca Berry for Special attacks
Again, as Age of Kings mentioned, they're not that special, but I suppose they have their uses.
Oh, and I should clarify that Custap Berry makes the holder "faster" for the next turn, i.e. priority modifiers still otherwise apply. That means that a Pokemon that has eaten a Custap uses, say, Reversal will still go second if the opponent uses Quick Attack.
