Numeric Facet Value Sorting

Is there any chance of Bloomreach offering Numeric Sorting of Facets vs. Alphabetic?

What is the best way to sort facets with numeric content from LOW to HIGH? Noting that most of our facets are not pure numbers, they also contain the measure unit i.e. inches, mm, cm etc.
I.e. Not: 1,10,11,12,13,14,15,16,17,18,19,2,20
but instead: 1,2,3,4,5,6,7,8,9,10,11

Additionally, how would you handle fractions going LOW to HIGH? Noting that most of our facets are not pure numbers, they also contain the measure unit i.e. inches, mm, cm etc.
