liamquin has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-selectors] add numeric comparisons on attribute values ==
Can we have numeric comparisons?

[data-balance<0] { color: red; } (common in accounting/finance, along with putting ( ) around the value)
[data-eyes>7.9] { color: black; background-colour: yellow } /* spider! */

with < <= >  >=

Noting that testing for equality is string equality so testing 06=6 fails, an alternative design might be to calc() to fetch an attribute value, and to be allowed in selectors, but that's more complex.

Maybe a new section inhttps://drafts.csswg.org/selectors/#attribute-selectors for Numeric Attribute Values?
