The bug could be seen by inserting tabs stops 1cm, 2cm, & 10cm. The
10cm tab stop would be inserted before 2cm since the comparison isn't
based on the numeric value.
The combobox to select the alignment in the paragraph format dialog

missing to set the alignment when OK button is pressed. This patch fixes
these issues.
