You could use three loops for getting this done. I think it should work but I cannot guarantee. :P

local players = getElementsByType("player")
local players_a = { }
local players_b = { }

for z = 1, #players do
  local p = players[ z ]
  if ( #players_a ~= #players ) then
    local s
    local p1_a = getElementData( p, "alivetime" )
    for i = 1, #players_a do
      local p2 = players_a[ i ]
      local p2_a = getElementData( p2, "alivetime" )
      if ( p1_a > p2_a ) then
        players_a[ i ] = p
        for x = 1, #players_b do
          local v = players_b[ x ]
          players_a[ x + 1 ] = v
        end
        players_b = players_a
  	  elseif ( i == #players_a ) then
        players_a[#players_a + 1] = p
        players_b = players_a
      end
    end
  end
end

You could use table.sort after line 62 in your script.

-- Descending
table.sort(playersTable,
	function(a,b)
		return tonumber(getElementData(a,"alivetime") or 0) > tonumber(getElementData(b,"alivetime") or 0)
	end
)

-- Or ascending
table.sort(playersTable,
	function(a,b)
		return tonumber(getElementData(a,"alivetime") or 0) < tonumber(getElementData(b,"alivetime") or 0)
	end
)

Assuming that your alivetime element data is integer.
