Joining two lists with relational operators

Thread[liste - listv <= 0] // Reduce
2 <= y <= 3 && z >= 4 && x <= 1
List @@ %
{2 <= y <= 3, z >= 4, x <= 1}

How do I reorder the inequities in an "alphabetic + numeric" order, such as {2 <= x1 <= 3, x2 >= 4, z <= 1}

Assuming there is one variable per inequality and there are no different length variables, e.g. x, x1, x12 at once, then:

#[[Ordering[Cases[#, s_Symbol /; Context[s] =!= "System`", ∞] & /@ #]]] &[
   {2 <= y <= 3, z >= 4, x <= 1}
]
{x <= 1, 2 <= y <= 3, z >= 4}

so at the end

Composition[
  #[[
    Ordering[
      Cases[
        #, s_Symbol /;  Context[s] =!= "System`", ∞
      ] & /@ #
    ]
  ]] &,
  Apply[List],
  Reduce,
  Thread
  ][liste - listv <= 0]
