ETA: Even if you needlessly choose to use quotes here, the period should be inside, from everything I've ever learned (and I edited books and magazines for three years).
ETA again:
This.
This rule applies even when the unit enclosed at the end of the sentence is just a single word rather than an actual quotation:
~To get to the next page, just press the little button marked "Enter."
The only exception is when that last little item enclosed in quotation marks is just a letter or a number, in which case the period or comma will go outside the closing quotation marks:
~The buried treasure was marked on the map with a large "X".
~The only grade that will satisfy her is an "A".
~On this scale, the highest ranking is a "1", not a "10".
