Why not:

Code:

stock const offsets[][2] = {{LS_START, LS_END}, {SF_START, SF_END}, {LV_START, LV_END}};
stock GetSpawnLocation(location, &Float:x, &Float:y, &Float:z, &Float:a) {
    new idx = random(offsets[location][1] - offsets[location][0]) + offsets[location][0];
    x = spawns[idx][0];
    y = spawns[idx][1];
    z = spawns[idx][2];
    a = spawns[idx][3];
}
