Are these bumpers legal? (Another bumper thread)

[Ginger Power]

This particular question has been debated by multiple LRI's and I've heard different opinions. Are these bumpers legal:

If you look at R28:

Team numbers must be displayed and positioned on the BUMPERS such that an observer walking
around the perimeter of the ROBOT can unambiguously tell the Team’s number from any point of
view and meet the following additional criteria:

A. consist of numerals at least 4 in. high, at least ½ in. in stroke width, and be either white in
color or outlined in white

B. must not wrap around sharp corners (less than 160 degrees) of the FRAME PERIMETER

The key word is "numerals" in bullet point A. If you look at the dictionary definition: Merriam-Webster
Dictionary.com
Oxford Dictionary

The logo is clearly a numeral by the dictionary definition, and it conveys the number 4607 unambiguously. So we don't have a problem right? By the letter of the law we should be legal, and I would love to hear the opinion of Big Al.
