Yep.  And this is a FAQ, caused by you using a locale that ignores 
punctuation when determining sort order.

https://www.gnu.org/software/coreutils/faq/#Sort-does-not-sort-in-normal-order_0021

If you are using new enough coreutils, try:

sort --debug a

for better understanding what is happening, then compare to:

LC_ALL=C sort --debug a

(if your sort doesn't understand --debug, then it is still useful to try 
LC_ALL=C sort a).
