My playerlist is acting very strange, its reacting to the starting digit only. Whats happening?

Picture: https://gyazo.com/526d5d557be31d1c0993d082f5315e5a Basically data is put into the table "playervals" and sorted by "RAP" which is a currency in my game.

Since the UIGridLayout sorts by name - in the for i,v loop it sets the name of the frame to a letter of alphabet (being first = a, being second = b etcetc) but whats strange is that if you had 715k and someone had 700b the person with 715k would be over them, someone please help

	local playervals = {}
	for i,v in pairs(game.Players:GetPlayers()) do
	if v:FindFirstChild("Values") and v.Values:FindFirstChild("Currencies") and 
             v.Values.Currencies:FindFirstChild("Bux") and 
             v.Values.Currencies:FindFirstChild("RAP") then
	            table.insert(playervals, {Name = v.Name, UserId = v.UserId, DisplayName = v.DisplayName, RAP = v.Values.Currencies.RAP.Value})
		end 
	end

	table.sort(playervals, 
		function(a,b)
			return a.RAP>b.RAP
		end
	)

	for i, v in pairs(playervals) do
		if v  then
			local player = nil;
			if findplrlist(v.Name) then
				player = findplrlist(v.Name)
			else
				player = templates.Player:Clone()
			end
		
			if v.VIP then
				player.Info.Username.TextColor3 = Color3.fromRGB(255, 207, 85)
			else
				player.Info.Username.TextColor3 = Color3.fromRGB(255, 255, 255)
			end
			
			if v.Name == game.Players.LocalPlayer.Name then
				player.SendButton.Visible = false
			end

			player.Name = abcs[i]
			player.Parent = UI.Playerlist.List
			player.Info.Username.Text = v.DisplayName
			player.Username.Value = v.Name
			player.Info.Level.Text = v.Level
			if lb == "RAP" then
				player.Info.Value.Text = ab.abbreviate(v.RAP)
			else
				player.Info.Value.Text = "????" .. ab.abbreviate(v.Bux)
			end
		end
	end
