Need help with a simple script pls?

I'm working with this simple texture-switcher by touch script. My question is, how can I change it so that the textures go in a certain order (number, alpha, whatever) instead of random?

Pardon my scripting ignorance. I did look all over the wiki and forums but couldn't find something I understood lol. Thx.

SCRIPT:

{

touch_start(integer total_number)
{
integer number = llGetInventoryNumber(INVENTORY_TEXTURE);
float rand = llFrand(number);
integer choice = (integer)rand;
string name = llGetInventoryName(INVENTORY_TEXTURE, choice);
if (name != ""
llSetTexture(name, ALL_SIDES);
}
}

integer choice = 1; //initialize this to one(not sure if this is best but it works)


touch_start(integer total_number)
{

string name = llGetInventoryName(INVENTORY_TEXTURE, (choice - 1));
if (name != "")
{
llSetTexture(name, ALL_SIDES);
}

else 
{
choice = 0;//if its a blank name start back at start
}

choice++;//next touch will be this texture # if you are counting from 1 the compiler counts from zero
}
}

this should work... however my same disclaimer applies..(im at work with no way to debug or test).. if anybody knows a more efficient way or sees a bug please fix it for me.

Tested and working.. paste it into your favorite state and let the texture switching begin
