comment Grid Lines in ListPlot
Does including Axes -> {False, True} or AxesOrigin -> {0, 0} have the desired effect (I am using Mma 7)?

comment Is there a “precedence table” for the canonical Sort ordering?
Sort@Transpose@{list, Ordering@Ordering@list} => {{0, 1}, {I, 2}, {0.1, 3}, {2, 4}, {2 + I, 5}, {2^x, 6}, {"y", 7}, {"Y", 8}, {"yy", 9}, {x, 10}, {2 x, 11}, {x^2, 12}, {x^x, 13}, {x^(2 x), 14}, {X, 15}, {xX, 16}, {xxx, 17}} and, as far as I know, the following (always?) holds: (Sort@mylist)[[Ordering@Ordering@mylist]] == mylist (see here).

Why not just solution /. (a[_] -> x_) :> x => {1, 10, 100}?

comment Select and Blank
My interpretation of the question is that the first value could be any one of "String1", "String2", "String3", "String4" (any first value). For example, what the OP tried was Select[test, (# == {_, "a"}) &]. No mention of string (lower-case) there. I know what my code does, btw.

But the OP did NOT say 'any string' (note the capital).
