I've done a quick test and in this case it works. Quickly tested your version 
number and then upgraded to 11_1_102_56:

Although I still recommend to use standard "dotted" notation as the above one 
works only because WPKG splits each part of the version number by non-numeric 
characters. So therefore 11_1_102_55 is not interpreted as "11.1.102.55" but as 
the expression 11_1_102_55 which is split into distinct numbers and then 
compared piece by piece.

But as said, in your case it works perfectly as long as you just use digits 
split by non-digit characters. Seamlessly 11v1v102v55 would work too.
