My Table 

[Store Number]	[opening closing time]	[opening closing time]	[Profit (%)]
----------------------------------------------------------------------------- 
1					8--10						100					  23	
2					9--10						70					  15
3					10--10						60					  8
4					8--8						95					  20
5					8--9						70					  17
6					9--9						85					  19		

I am able to sort the data asc and desc order where the data is in int value but not where data in 
string. Here in example i could not sort the column [opening closing time] as it has to be sort
by the time interval difference. How do i achieve this ? I need to implement sort functionality in all
column. Rest 3 columns works as desired. But i do not know how do i implement sorting in 
[opening closing time] column? 


My HTML
<table>
<thead>
	<tr>
		<th ng-click="sortRdata('StoreNum')">Store Number</th>
		<th ng-click="sortRdata('OperatingHours')">opening closing time</th>
		<th ng-click="sortRdata('AvgCustNum')">opening closing time</th>
		<th ng-click="sortRdata('Profit')">Profit (%)</th>	
	</tr>
</thead>
<tbody>
		<tr ng-repeat="r in StoreReports|orderBy:sortRcolumn:reverseRsort ">
		 <td>{{::r.StoreNum}}</td>
         <td>{{::r.OperatingHours}}</td>
         <td>{{::r.AvgCustNum}}</td>
         <td>{{::r.Profit}}</td>
		</tr>
</tbody>
</table>


Javascipt Code:
    $scope.sortRcolumn = "StoreNum";
    $scope.reverseRsort = false;

    $scope.sortRdata = function (column) {
        $scope.reverseRsort = ($scope.sortRcolumn == column) ? !$scope.reverseRsort : false;
        $scope.sortRcolumn = column;
    }

What I have tried:

$scope.sdata = function (OperatingHours) {
       var operatingHrArray = operatingHours.slpit('');
       var openingHour = parseInt(operatingHrArray[0]);
       var closingHour = parseInt(operatingHrArray[3]) + 12;
       return closingHour - openingHour;
   }
