Find a dimension by it's length with a fuz factor?

[hutch]

The dimension is stored as data in my application.
A typical dimension might be 12'-0 1/2" or 144.5
but the following ssget doesn't find it because the dimension is actually "144.425" (for instance).

(ssget "x" (list (cons 0 "Dimension") (cons 42 "144.5")))

how can I do this but incorporate a 'fuzz' factor so that my app finds the dimension?
