There was a change in pst-plot.tex after the initial 2010 TeX Live distribution, which changed the behavior of labels in cases such as you describe. I reloaded my 2008 and 2009 TeX Live distributions and verified that the behavior is now different. Until Herbert has researched this and provided a fix, here is a method that does not involve editing hundreds of files. Search your current distribution for a file named pstricks.con. (kpsewhich pstricks.con will tell you the path.) Open it in a text editor which can edit system files (after you authorize it, of course)---for example TextWrangler (free) from bbedit.com.  There is a customization section into which you should insert the following:

\pstcustomize
\AtBeginDocument{%
  \ifx\PSTplotLoaded\endinput %
    \define at key[psset]{pst-plot}{ticks}[all]{%
    \pst at expandafter\psset@@ticks{#1}\@nil\psk at ticks%
    \pst at expandafter\psset@@ticks{#1}\@nil\psk at labels}
  \fi}%  
\endinput

The effect is that every time you load pstricks, that block is input, and if pst-plot has been loaded by the end of the preamble, you will redefine 'ticks' so that it changes 'labels' to the same value. Make a note of what you did so that you remember to remove everything up to  \endinput when a fix is provided.
