In her ruling, Miles-LaGrange found that the amendment was a solution in search of a problem.

Miles-LaGrange found "that any harm that would result from permanently enjoining the certification of the election results is further minimized in light of the undisputed fact that the amendment at issue was to be a preventative measure and that the concern that it seeks to address has yet to occur."

She pointed out in a footnote that attorneys defending the amendment at the November 2010 preliminary injunction hearing admitted that "they did not know of any instance where an Oklahoma court had applied Sharia law or used the legal precepts of other nations or cultures."

She also determined that merely striking out the anti-Sharia provisions was not an option.  Not only did the pro-amendment campaign harp exclusively on the Sharia provisions, but she also determined that it would have neither been passed by the legislature nor approved by the voters had those provisions not been there.  Most damningly, she pointed out that the portion about "legal precepts of other nations and cultures" was not included in the ballot title.  Therefore, striking out the anti-Sharia provisions would result in amending the Oklahoma constitution by implication, which is forbidden.

While there's no word yet on whether Oklahoma will appeal, the prospects don't look that great for this decision to be overturned.  According to Wikipedia, of the ten active judges on the 10th Circuit, five were appointed by Republicans (one by Bush 41, four by Bush 43).  And two more Obama appointees are pending in the Senate.
