autom8 rules and greater than comparison

[meralias]

Is there any reason why the >=, >, < and <= operators (when creating rules) are using string comparison, rather than numeric comparison (or at least offering you the choice to use string vs numeric) ? The reason that I ask is that I'm writing some graph rules based on whether ifSpeed is greater than a certain value, and doing a string comparison with '>' means all ifSpeed values that are greater than 0 are being matched.
