Not sure where you put the resource. Something like this should work:

   <DataGrid>
      <DataGrid.Resources>
        <Style x:Key="AlignRight" TargetType="DataGridCell">
          <Setter Property="HorizontalContentAlignment" Value="Right" />
        </Style>
      </DataGrid.Resources>
      <DataGrid.Columns>
        <DataGridTextColumn CellStyle="{StaticResource AlignRight}">
           </DataGridTextColumn>
      </DataGrid.Columns>
    </DataGrid>

Or, if the alignment is only used for the one column you could just do it inline:

    <DataGrid>
      <DataGrid.Columns>
        <DataGridTextColumn >
          <DataGridTextColumn.CellStyle>
            <Style>
              <Setter Property="FrameworkElement.HorizontalAlignment" Value="Right"></Setter>
            </Style>
          </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
      </DataGrid.Columns>
    </DataGrid>
