recognizing date ranges 
i have a spreadsheet that logs various issues by date, then automatically counts each type by week and by month. i have it set up so that the week and month titles automatically generate, so that when i put in a new entry for a given week the heading is automatically created. example:

       Input page                                      Tabulation Page

      A             B                              A                        B             C

    Date        Issue                        Week                  Issue 1    Issue 2

12/10/2012  Issue 1           12/16/2012-12/22/2012        0            1

12/10/2012  Issue 1            12/9/2012-12/15/2012         2            1

12/11/2012  Issue 2

12/17/2012  Issue 2

the problem comes where gdocs doesn't recognize "12/9/2012-12/15/2012" as a date range. the first cell (which says 12/16/2012-12/22/2012) contains a formula (thanks to someone on this forum!) like =SORT(ArrayFormula(filter(unique(if('Input page'!$A$2:$A="","",'Input page'!$A$2:$A-weekday('Input page'!$A$2:$A)+1&"-"&'Input page'!$A$2:$A+(7-weekday('Input page'!$A$2:$A)))),unique(if('Input page'!$A$2:$A="","",'Input page'!$A$2:$A-weekday('Input page'!$A$2:$A)+1&"-"&'Input page'!$A$2:$A+(7-weekday('Input page'!$A$2:$A))))<>""))). this sort recognizes "9" as being greater than "1", instead of seeing that it is less than "16", thus throwing off the sort

is there a way to get gdocs to recognize this date range? if not, how might one work around this? the monthly side works until a changeover in year, then of course january takes over!
