abase == abate == might? I guess I'm too stupid.

I suppose "powre" is four times a typo.
her == his == their? Or are there three different sets of lines, one of
them a singleton?

This sounds like a "decorate - sort - undecorate" problem:
1. Put each line into "sortable" order (in this case, reverse the order
of the terms, so that the last term comes at the start of the line, then
one space, then the last but one, then one space, etc.);
2. Sort
3. Put the lines back like they used to be (i.e., reverse the order of
the terms again).
Note that no "dumb" computer will be able to find out that "his", "her"
and "their" are to be sorted together, unless you somehow program it
into the logic of your steps 1 and 3.
Best regards,
Tony.
