Those value are already ordered, not as numbers but as strings and there is nothing you can do about it.
If you really want to have them ordered (tag values are always ordered in an alphanumeric ascending way by default) you need to add the leading zeroe (es: 1 -> 01), this will result in a correct sorting.
Also I suggest you to renae this question to something more on-topic, you are asking how to order the legend of a grafana chart, ot how to drop a measurement
