How do I do the wording on this cake?  

One way is to print out the label in big size and the cut out the letters and put them on fondant and cut out the letters.

or you can check out this link,. There are some free fonts underneath which look similar and use those. The no.7 has to be cut out by taking a print. I dont think there is any font system which looks like that.

Her suggestion is definitely the easiest way. The wording on the cake all look to be hand painted, and you can check YouTube for tutorials on how to go about doing that.

I zoomed in really closely and I do not believe the lettering or the scrolling is hand done.  It is too perfect.  As a commercial artist (retired), I believe it is virtually impossible to freehand this cake.  I am guessing it is printed on edible sheets.

Not impossible at all. I've seen cakes done with freehand lettering, not something that can be done without lots of practice. 

Lettering is done using an edible image

I've seen cakes done with freehand lettering, too, but not like this.  I doubt even a professional sign painter could make letters this perfect and identical.
