It's comparing by a string rather than by decimal.  

Update your code to ignore the $.

string_x = item_x.SubItems(m_ColumnNumber).Text.Replace("$","")

string_y = item_y.SubItems(m_ColumnNumber).Text.Replace("$","")

I tried this and it does the same thing.
If Decimal.TryParse(Replace(string_x, "$", ""), flags, Nothing, dec_x) And Decimal.TryParse(Replace(string_y, "$", ""), flags, Nothing, dec_y) Then

With the code the way it was to start with, at the break point I can see that the value of dec_x and dec_y are in fact decimal values.

Are you using a string format to set the currency?  What if you take that out?  Does it work?

I am using formatCurrency for the item in that column.
lstItem.SubItems.Add(FormatCurrency(reader.Item("IDTCost"), 2))

When i take it out it sorts properly.
I dont know why it is not working the way it is setup already. The TryParse is working using the flags and dec_x and dec_y are converted to decimal properly.

Add this to your flags:

'... = the other globalizations you already have.  Add AllowThousands at the end.

flags = ... OR ... OR System.Globalization.NumberStyles.AllowThousands
