Headings like "Query" are more likely to be ignored and just create
the impression that you gave no thought to creating an informative
title.

Typing http://web.missouri.edu/~kolenikovs/stata/polychoricpca.hlp
shows where this command comes from, which you are asked to explain.

The option -score()- is explained as follows

score is the prefix for the variables to be generated to contain the principal
    component scores.

So you are right.
