I believe you could use sscanf to split the entry by using comma as the delimiter.

pawn Код:

public OnPlayerText(playerid, text[]) {
    new
        Float: fCoordinates[3];

    if(sscanf(text, "p<,>fff", fCoordinates[0], fCoordinates[1], fCoordinates[2])) 
        return 1; // Error: Invalid coordinates

    SetPlayerPos(playerid, fCoordinates[0], fCoordinates[1], fCoordinates[2]);
    return 1;
}

However, the spaces should be removed between the coordinate text. (140.17,1366.07,1083.65)
