# Sorts the issues for the given IDs.
#
# This method runs a single SQL query using a CASE statement to update the
# position of all issues in the current milestone (scoped to the list of IDs).
#
# Given the ids [10, 20, 30] this method produces a SQL query something like
# the following:
#
# UPDATE issues
# SET position = CASE
# WHEN id = 10 THEN 1
# WHEN id = 20 THEN 2
# WHEN id = 30 THEN 3
# ELSE position
# END
# WHERE id IN (10, 20, 30);
#
# This method expects that the IDs given in `ids` are already Fixnums.
