You should set pointRange parameter, like in the example: http://jsfiddle.net/sbochan/X4UJd/1/

score:0

As a very quick fix, you can put what value is lower to display second so it appears in front of the other one.

series: [{"name":"pass","data":[{"x":1367391600000,"y":2}]},{"name":"warning","data":[{"x":1367391600000,"y":1}]},{"name":"fail","data":[{"x":1370070000000,"y":1}]}]

This way the height of 2 will be drawn and then the height of 1 so you can see both.
