Greatest to Least without table.sort()?

If I gathered numbers within a table or without and need them greatest to least without using table.sort().

If you need a list sorted, it doesn't make sense to reinvent what's already been given to you. Sorting is moderately difficult to get right, and in any case you will need to implement the comparison function you'd be giving to table.sort in the first place.

If you wanted to sort a list of these items by their .rap, you could use something like this:

function descendingRAP(a, b)
	return a.rap > b.rap
end

table.sort(Items, descendingRAP)

Another option, instead of using table.sort, you can just insert the item into the proper place:

function add(element)
	for i = 1, #list do
		if element < list[i] then
			table.insert(list, i, element)
			return
		end
	end
	table.insert(list, element)
end

where element < list[i] could be replaced by any less(element, list[i]), where less is the function you would pass as the second parameter to table.sort.
