    LP#1511828: sort proximities numerically when targeting holds
    
    The hold targeter had three instances of using lexical sorting
    rather than numerical sorting.
    
    Two of the instances affected hold targeting if proximity values were
    over 9.  Proximity values were being sorted lexically. For instance,
    1,2,5,11,15,100,120 was sorted as 1,100,11,120,15,2,5, causing
    interesting hold targeting results. Normally proximity doesn't go
    that high so it isn't a problem, but we were using proximity adjustments
    to strictly order locations so each location had a different proximity,
    driving the numbers above 9.
    
    One instance wasn't causing any current issue but could cause problems in
    the future if more best hold selection sort options are added to bring the
    total number of sort options over 9.
    
    Also included are some changes to reduce warnings in the logs
    suggested by Bill Erickson.  The sorting problem was found by
    Galen Charlton, thanks Galen.
    
    Testing Notes - to trigger this issue you need to have adjusted
      proximities over 9.
    
    1. Use proximity adjustment rules to add a +10 proximity adjustment to
      one item circ lib, Branch A and a +2 proximity adjustment to the
      item circ lib Branch B.
    
    2. Find a title with a copy at Branch A and B. Place a hold with a
      pickup location of Branch B.
    
    3. The copy at Branch A should get targeted since it has a proximity of
      12-14 (10+normal proximity) and Branch B has a proximity of 2
      (2+normal proximity).  12 gets sorted before 2 lexically.
    
    4. After the fix the copy at Branch B should get targeted since 2
      is sorted before 12.
